This model is one of the easiest to assemble, disassemble and clean. It is also fully waterproof, so you can wash it after each use.
My favorite feature is the sleek and durable design, as the silicone feels great against your skin and the hollow doesn’t squeeze too tight. That said, some men might find it too small, depending on their girth.
The set comes with three shaft sizes and shapes and they all bring something new to the table. My boyfriend and I had a blast with each one and the sizing suited him perfectly.
Bottom line: the best beginner set – 3 shaft sizes, waterproof, easy clean. Hollow may run tight for wider girths.
Fetish Fantasy Unisex Extreme Hollow Strap-On
Most Effective
Experienced users who have already used large hollow straps.
Expert: For those who have extensive experience. Offers advanced features and capabilities, demanding in-depth knowledge and skills.
- Material: PVC
- Power source: None
- Allergens: Contains Latex, Phthalate-Free
- Length: 266.7 mm / 10.5 in
- Maximum harness size: 1270 mm / 50 in
- Internal length: 152.4 mm / 6 in

- Boosts erection and delays ejaculation
- 100% waterproof and easy to clean
- Cons
- Contains traces of latex
- Could be too big for those inexperienced with dildos
This strap is rather bulky, so using it takes some practice and requires prior experience. However, it’s easy to put on and fasten and the harness is highly adjustable.
In terms of boosting erections and delaying ejaculations, this one is a definite star. It made my boyfriend last so much longer and I enjoyed every torturous second of the ride.
The only potential problem is that the dildo is made of PVC and that it contains traces of latex. Though these facts make it affordable, it’s important to remember that these materials aren’t the safest options you can go for.
Bottom line: the most realistic feel pick – intricate veins, remote vibration modes, firm build. Not for users who prefer flexible dildos.
Lovehoney Perfect Partner
Most Realistic
Intermediate users who want a quality, non-rechargeable dildo.
Adept: Aimed at users with some familiarity. Balances user-friendliness with more sophisticated features.
- Material: PVC
- Power source: 2 x AA Batteries (not included)
- Allergens: Latex-Free, Phthalate-Free
- Length: 215.9 mm / 8.5 in

- Insertable length: 203.2 mm / 8 in
- Circumference: 158.75 mm / 6.25 in
- Canal diameter: 38.1 mm / 1.5 in
- Waterproof: Splashproof

- Pros
- Contours, veins and bumps make for a realistic feel
- Both partners can control the vibration mode via the wired remote
- Extremely comfortable and easy to put on
- Cons
- Might be too rigid for some users
- Batteries are not included in the package
If you like your toys extra realistic, this model is the one for you. The veins and ripples feel exquisite against the skin and the pleasure builds with every new thrust.
The toy is rather easy to put on, so you won’t have any issues even if you aren’t that experienced. Changing the vibration modes is also effortless, since you can do it both on the toy itself and via the remote.
I typically prefer firmer straps, so this one felt heavenly to me. However, if you are more into flexible and pliable models, you might find this one lacking.
Bottom line: the best for erection support and ejaculation delay – highly adjustable harness, torturous endurance. PVC + latex materials are the trade-off for the affordable price.

- Super easy to clean
- The material is hypoallergenic and odorless
- Cons
- The surface is smooth and not at all realistic
- Some might find it too stiff
Both the harness and the strap are made of premium-quality silicone, which is a big advantage. The toy feels incredible against your skin and its smooth surface only adds to the appeal.
Naturally, you won’t dig this one if you like more realistic designs, But in terms of ease of use and insertion, you will be hard-pressed to find a better model.
The material is highly breathable and hypoallergenic. It is also odorless and cleaning it is a true breeze after every use since you can just wash it with warm water and a cleaner.
Bottom line: the best material quality – premium silicone inside and out, hypoallergenic, odorless, breeze to clean. Smooth surface means no texture sensation.
Doc Johnson Body Extensions Be Daring
Best Unisex
Novice users of any gender who want to buy their first hollow strap.
Rookie: Perfect for users who are new to this type of product. Focuses on simplicity and ease of use.
- Material: Silicone & Elastic Harness
- Power source: None
- Allergens: Phthalate-free - Non-porous
- Total Length: 177.8 mm / 7 in
- Width / Diameter: 44.5 mm / 1.75 in
- Circumference: 146.1 mm / 5.75 in
- Harness fits waists: 710 to 1210 mm / 28 to 48 in
- Waterproof: Submersible

- Pros
- Unisex, so suitable for everyone
- The harness is fully adjustable and comes with elasticized bands
- Includes a detailed instruction manual for use and maintenance
- Cons
- The surface is too smooth, so the feeling is not realistic
- Some might find it a bit too stiff
This toy is entirely unisex – both the dildo and the harness can be worn by a person of any gender. The fit is excellent, the harness adjustable and the entire contraption is extra easy to use.
I’m not a newbie by any means, but even I appreciated the detailed instruction manual included with the strap. It explains every step of assembly, use and maintenance, which is fantastic.
I have to say I usually like my dildos more realistically designed, so the smooth surface did little for me. Still, it’s a great option for beginners!
Bottom line: the most inclusive and beginner-friendly – unisex design, detailed instruction manual, adjustable harness. Smooth surface suits beginners better than texture-seekers.
Pipedream 7" Hollow Rechargeable Strap-On
Best Details
Intermediate users looking to try out their first strap-on toy.
Adept: Aimed at users with some familiarity. Balances user-friendliness with more sophisticated features.
- Material: PVC, ABS plastic
- Power source: Rechargeable
- Battery power source: 2 AA batteries (not included)
- Allergens: Phthalate-free - Non-porous
- Size: 187.96 x 43.18 mm / 7.4 x 1.7 in
- Insertable length: 177.8 mm / 7 in
- Waist size: Fits up to 1 320.8 mm / 52 in
- Warranty: 90 days
- Pros
- The hollow core design ensures anyone can wear it
- 10 vibration, pulsation and escalation modes
- A single charge lasts about 2 hours
- Cons
- Made of PVC, which is not the safest and sturdiest material
- Can be difficult to clean and maintain
This bad boy offers you 10 brilliant modes of escalation, pulsation and vibration. It’s a real delight to use and the 2-hour battery life is just enough to allow for longer sessions.
I really appreciated the anatomically accurate details on the surface of the dildo. They rub against your inner walls perfectly and the size and girth of the shaft ensure you feel each little detail.
Since it is made of PVC, this strap isn’t really built to last. Plus, the material isn’t as safe as silicone, so I expect that many might find it uncomfortable or dislike the feel.
Bottom line: the best vibrating pick for the price – 10 modes, anatomically detailed, 2-hour battery. PVC material means shorter lifespan than silicone.
Fetish Fantasy Ejaculating Hollow Strap-On
Best Ejaculating Model
Seasoned players who want to try ejaculating toys.
Expert: For those who have extensive experience. Offers advanced features and capabilities, demanding in-depth knowledge and skills.
- Material: PVC
- Power source: None
- Allergens: Phthalate-Free
- Length: 215.9 mm / 8.5 in
- Insertable length: 190.5 mm / 7.5 in
- Circumference: 158.75 mm / 6.25 in
- Canal diameter: 44.45 mm / 1.75 in
- Waterproof: Submersible
- Warranty: 90 days
- Pros
- Comes with a liquid reservoir at the tip
- The harness waist is adjustable and suits most bodies
- 100% submersible, so you can use it in the tub or shower
- Cons
- It’s a bit difficult to clean
- Too expensive for a relatively simple hollow strap
This strap resembles some of the simpler models on the market, but it has one big advantage. It comes with a liquid reservoir that you can fill up to make your orgasms even more realistic.
The toy is fully submersible, so you can enjoy it in the bath and shower as well. However, due to the reservoir, cleaning the toy isn’t the easiest task.
I love that the harness is fully adjustable and I think it will suit most body types. The dildo itself is textured and pretty long, so I had an awesome time using it.
Bottom line: the most realistic finish experience – liquid reservoir, fully submersible, adjustable harness. Reservoir makes cleaning more complex; store empty.
Doc Johnson Body Extensions Be Bold
Most Comfortable
Intermediate users who want a smooth but pleasurable toy.
Adept: Aimed at users with some familiarity. Balances user-friendliness with more sophisticated features.
- Material: Silicone & Elastic Harness
- Power source: None
- Allergens: Phthalate-free - Non-porous
- Total length: 203.2 mm / 8 in
- Width / Diameter: 50.8 mm / 2 in
- Circumference: 177.81 mm / 7 in
- Fits waists : 710 to 1210 mm / 28 to 48 in
- Waterproof: Submersible
- Warranty: 90 days
- Pros
- Suitable for both men and women
- Excellent for men who have erectile dysfunction
- The harness is adjustable and has wide elastic bands
- Cons
- The material is a bit flimsy
- The surface is smooth, so there’s no added inner stimulation
Since it’s designed to suit both men and women, this toy allows you to have a lot of kinky fun. The smooth surface ensures insertion is effortless, although it does not provide any additional inner stimulation.
When you lube up this toy, the surface starts feeling somewhat flimsy to the touch. Now, it’s not of low quality by any means, but it did irk me a bit, considering the toy’s price.
This strap is an excellent voice for those who have erectile dysfunction or want to build stamina. Still, I think seasoned players will definitely need something more advanced.
Bottom line: the best ED support option – specifically designed for users with erectile dysfunction, effortless insertion, stamina-building. Lubed surface feels slightly flimsy at this price point.
Fetish Fantasy 10 Inch Hollow Dreams Strap-On
Best Harness
Intermediate users who want to move on to slightly more demanding straps.
Rookie: Perfect for users who are new to this type of product. Focuses on simplicity and ease of use.
- Material: TPR
- Power source: None
- Allergens: Phthalate-free
- Length: 266.7 mm / 10.5 in
- Insertable length: 241.3 mm / 9.5 in
- Width: 50.8 mm / 2 in
- Inner diameter: 38.1 mm / 1.5 in
- Waist size: Up to 1 219.2 mm / 48 in
- Weight: 415 g / 14.64 oz
- Waterproof: Submersible
- Warranty: 90 days
- Pros
- Strap designed for comfort and support
- The harness is extra elastic
- Made of a phthalate-free, body-safe material
- Cons
- Has a bit of a stiff, plastic feeling
- It’s tricky to clean
This strap and harness are designed with comfort in mind. As a result, putting them on is truly a seamless experience and it will feel that way even if you have never touched a strap before.
Made of TPR, the dildo feels quite soft, smooth and realistic. However, it does have a bit of a plastic feeling and the stiffness isn’t the usual firmness that you’ll enjoy if you love rough sex.
Still, the pricing is incredible, the toy is quite long and thick and the shaft is curved deliciously. So, you win some and you lose some!
Bottom line: the best value XL pick – excellent price, curved shaft for G-spot access, TPR softness. Slight plastic feel; not ideal for rough sex.
Lux Fetish Unisex Vibrating Hollow Strap-On Dildo
Best Look
Middle-grade users who want to try a vibrating hollow strap.
Rookie: Perfect for users who are new to this type of product. Focuses on simplicity and ease of use.
- Material: ABS, Nylon, PVC
- Power source: 2 AAA batteries (not included)
- Allergens: Phthalate-free
- Size: One size fits most
- Pros
- Made to fit most sizes thanks to the stretchy waistband
- Crafted from phthalate-free PVC, nylon and ABS plastic
- Features a hollow penis and side controller with 7 vibrating options
- Cons
- AAA batteries are not included with the product
- Doesn’t come with a storage bag
This stretchy waistband harness can accommodate most sizes and it is quite light to wear. The dildo is just as convenient, so moving with the strap isn’t clunky at all.
Although the toy is battery-powered, the vibration patterns and intensities it offers are rather varied and strong. There are 7 to choose from and I had a fun time with each one.
Now, this strap is made of a combination of PVC, nylon and ABS plastic. As such, it is odorless, safe to use and phthalate-free, although it likely won’t last as long as silicone models.
Bottom line: the lightest and most wearable – stretchy waistband, 7 vibration patterns, phthalate-free. PVC/nylon/ABS won’t last as long as pure silicone.

Back To The Top 10 Hollow Strap-Ons
Hollow Strap-Ons: Boost His Size and Supercharge Your Pleasure!
“There are so many jokes about size. And what do they all share in common? Well, at the end of the day, what matters most is whether the experience actually hits the right spots for you. That’s where hollow strap-ons come in.”
Firstly, I’m not trying to humiliate your male lover’s penis, no sir. I’m just sayin’ that women have needs… That’s exactly where hollow strap-ons come in! They’re some of the most overlooked sex toys out there. But if you only do a simple search online, you’ll see thousands of guys and gals enjoying their incredible size-boosting abilities. But can you actually use them for super-strong orgasms with a size-boosting toy?
The Easiest Way to Upgrade Your Partner’s Size
Whether you’re someone who craves more depth during penetration, needs more girth to reach the right spots, or just wants a fuller experience than your current dynamic provides – hollow strap-ons are the most direct solution available. Even others who are not so perverted (it’s never too late to begin!) will have problems climaxing during penetration.
It’s true – sometimes, that penis just won’t reach that sweet spot. Whether you’re one of those ladies or you’re craving something else entirely, these toys can transform your partner’s size with 2-4 extra inches and give you the deep, filling sensation you’ve been looking for!
Hollow Strap-on Dildos Explained
Basically, these strap-ons look like good old classic strap-ons. They typically include a wearable harness paired with a strap-on dildo. If you’re familiar with adult content or simply exploring different forms of intimacy, you may already have an idea of how they’re used.
If not, all strap-ons are vibrators or dildos that you can attach to your body. When you wear one, it can give you a sense of experiencing intimacy from a different perspective. However, hollow strap-ons aren’t typically intended for same-sex female use – they’re specifically designed to fit over a penis.
You can probably see the idea. A hollow strap-on includes a harness and a dildo with an internal cavity. When aroused, the wearer can put on the harness and fit themselves inside the toy, creating the effect of a larger, more pronounced shape.
It’s straightforward and can be quite effective. These toys aren’t just about one person’s experience either – they can add something new for both partners. When worn, they can create a different sensation and visual dynamic, while the soft, hollow design is made to feel comfortable around the penis.
The mechanics are simple: he wears the hollow dildo over his own anatomy. Then, when he penetrates you, you feel the dildo’s full size and girth – not just his natural size. The sensation for both of you is genuinely different from anything else.
Benefits of Hollow Strap-Ons for Couples
Part of the reason why these strap-ons are often overlooked is that some men could have a problem discussing their penis size. If you want to convince your male partner to try a fake hollow penis with you, just show him the following:
- Instant orgasm boost -These strap-on toys will prolong his erection and supercharge his orgasms!
- No condoms needed! – Since the entire hollow dildo is made of a thick and sturdy material, your guy will get to come inside all he pleases. No need to worry about getting knocked up! Plus, if he hates condoms, he’ll never have to wear one. The hollow dildo will form a perfect contraceptive barrier.
- Long sex marathons – This toy will help with any numbness that your man might feel during longer sex sessions. That is especially useful if you take longer to come.
- No more floppy poppy – Hollow dildos are actually a useful medical tool. They can help men who are suffering from erectile dysfunction. If your guy can’t get it up, you can still have intense sex with him if he wears this toy!
Types of Hollow Strap-Ons
Here’s where we get to the fun part: choosing your perfect strap-on! As I said, there are tons of options on the market. One way to narrow them down is to check out all the different types:
Non-Vibrating Hollow Strap-Ons
Since most non-vibrating strap-ons are made to be worn by men, they’ll have a hyper-realistic design. The actual dildo will be finely crafted to look just like a huge thick penis! *Droooool*
The rest is pretty simple: realistic hollow strap-ons are made of soft materials like silicone. Your guy will feel super comfortable while wearing them. If you pick the right size, they’ll follow the natural shape of his penis while feeling like an extra-tight Fleshlight.
Vibrating Hollow Strap-Ons
Besides giving your lover an ultra-large penis, realistic hollow strap-ons can also boost your pleasure with powerful vibrations. The way this works is that the dildo will usually have a built-in vibrating toy. It will also come with a remote that lets you configure the pulsation settings. So expect to feel deep rumbles all over your body, deep down internally and all over your partner’s new fake penis!
Extra Large Hollow Strap-Ons
If extreme sizes aren’t your preference, you can choose a hollow dildo that offers a more average and comfortable fit. However, I know your deepest and darkest fantasies! If you’re a size queen and you’re not satisfied with anything below 7 or 8 inches, this is the toy for you.
An XL strap-on will deliver the most filling, intense experience you’ve ever felt. These toys are usually over 8 or 9 inches long. Some of them can get as big as 12 or 14 inches! They’re designed to cater to a wide range of fantasies and imaginative roleplay scenarios. Just remember: I wouldn’t recommend these huge toys if you haven’t trained for larger sizes before.
Explore Other Kinky Options:
- Dark-coloured strap-ons – Available in a full range of skin tones and colors, including deep brown and dark shades. Choose the aesthetic that appeals most to you and your partner.
- Squirting strap-ons – If you or your lover are avid semen enthusiasts, these types will deliver a torrential realistic finish from the internal reservoir! Just strap your partner in and make him use your body as target practice!
- DP hollow strap-ons – If you’ve always wanted to experience dual penetration with a single partner but you never wanted to involve another man, these types are perfect for intense DP play!
- Strapless Penis Sleeves – Penis sleeves are a whole other category of sex toys, but they’re also used to give your guy a size boost. The biggest difference here is that they don’t require a harness. This could be useful if your partner isn’t comfortable with wearing a harness.

Buying the Best Hollow Strap-On
Which of those types excites you the most? I told you you’d have some option anxiety! Of course, you don’t need to try every option out there. Instead, follow these tips to help you choose the strap-on that suits you best:
Hollow Strap-On Mistakes to Avoid
- Not measuring your partner’s girth before buying – the hollow interior needs to accommodate your partner’s girth comfortably. Too tight causes pain; too loose means the toy moves around. Always check the interior diameter specification before purchasing.
- Skipping the lube – even with a highly aroused partner, lube is essential for comfortable insertion of the hollow dildo. Water-based only for silicone and TPE models.
- Not discussing it with your partner first – this is the most important step. A hollow strap-on that arrives as a surprise can feel like a comment on his size rather than an exciting new toy. Frame it as a shared adventure, not a correction.
- Starting with XL on the first attempt – if neither of you has experience with larger sizes, jumping straight to 10+ inches can be genuinely uncomfortable. Start 2-3 inches above his natural size and work up.
- Not cleaning the internal channel thoroughly – the hollow channel collects more residue than a standard toy. Flushing with water alone is not sufficient. Use a bottle brush or finger to scrub the interior with soap after every use.
How to Get It Right the First Time
- Think about how you’re going to use your strap-on. Do you simply want a size boost? Or do you want to help your guy fix his ED problems? Some hollow toys are specifically designed for some purposes like intense sex. Others are made to help people with ED.
- Discuss everything with your partner. Don’t catch your lover off-guard and force him to wear this toy. Instead, talk things over and explain how both of you could have fun with this strap-on.
- Choose the type and look you like the most. Obviously, you don’t have to get a giant strap-on if the size intimidates you. You can choose any size or color you like!
- Don’t ignore the fit. While you should find the size and girth that you prefer, your partner’s sensations are equally important. Some strap-ons can be too tight on the inside. That’s why it’s essential to consider your guy’s initial length and thickness.
- Warning: don’t overestimate your abilities! If your partner already has an average-sized penis, adding just a few inches could make it feel like too much too fast. Unless you’re very experienced, remember: too small is mildly disappointing, too big can cause real discomfort.
#1 Rule: The Attachment Style Will Make All The Difference
Besides a wide variety of dildos, sizes and shapes, you also have to pick the right harness. So check out which one is the most comfortable:
- One-piece type – These are a decent budget option, but you won’t be able to remove your dildo from it. A one-piece harness will usually resemble underwear, kinky BDSM thongs, etc.
- Strap-style attachment – This is the most classic attachment style. It consists of a harness with multiple adjustable straps. It secures a comfortable fit. Plus, it will feel like a natural extension of your lover’s penis. But, you’ll get more balance out of your harness if you get one with three or more straps.
- Removable dildo harness – Some harnesses have O-rings or holes. They allow you to attach nearly any type of hollow dildo. This is the best option if you want to experiment with various sizes and shapes.
The Safest Hollow Dildo Materials
Since this toy will go inside your body and around your partner’s disco stick, it’s crucial to weed out the lemons. You should focus only on the toys that use the safest materials:
- Silicone – Silicone hollow strap-ons are the highest quality toys you could get! This material is 100% body-safe and non-porous. Also, silicone hollow strap-ons create a smooth lifelike feel. Even better, this material is the easiest to clean and sterilize.
- TPE – Since silicone is the safest, it’s also the most expensive. If you’re on a budget, a TPE dildo could do the trick. However, TPE is porous and it can absorb bacteria. Still, you can use it if you know how to clean it properly before AND after your rodeo.
- Plastic – You’ll also encounter hollow dildos made of hard plastics. Honestly, these are just OK. While materials like ABS plastics are body-safe, they’re not the best choice for hollow strap-ons since they have an unyielding shaft.
And what about the baddies? Well, you’ll always encounter some cheap options made of unsafe materials. That could include PVC, rubber, fake silicone and jelly. Those materials contain a substance known as phthalates. Honestly, they shouldn’t go anywhere near your body!
Look and Feel
Now, this is where you and your partner will need to put your thinking caps on. Think about the dildo that drives you both wild!
For example, if you love to get your G-spot pounded until you squirt, pick a curved dildo. What if you love it when your partner stretches out your sphincter? Hmm, why not choose an extra-wide dildo and make for a wide, intense stretch that experienced users love. But if my disturbing fetishes are frightening you, you can always choose a subtle non-phallic toy.
Choosing the Right Size
When it comes to size, you should start with your partner’s waist measurements to find the best harness.
After that, consider the size, girth and the width of the hollow hole. Most hollow dildos will fit the average penis. However, some could be too tight. So make sure you measure your partner’s girth. Then, choose a length and external girth that turns you on the most.
As mentioned, this can be as big as 14 inches, but most people can’t comfortably fit that much length internally. Remember, your realistic hollow strap-on could be just a few inches bigger. That will be perfectly enough to satisfy you! Of course, if your holes are already trained, you can go as big as you want!
Extra Features
Most hollow strap-on dildos are pretty basic and they don’t come with a whole host of features. However, you’ll still encounter various vibrating hollow strap-ons, fake textured dongs, remote control options and more.
If you want to get something that will offer you an extra kick, always look into the features to see if they’re worth paying extra for. As an example, vibrating hollow strap-ons need to have a quality mechanism. In most cases, they will provide you with an insertable bullet vibe. Plus, you’ll get around 10 or more vibration settings.
In my experience, you’ll do your best if you stay away from vibrating hollow strap-ons that are attached to a bunch of cables or those that only give you only two or three settings. Additionally, don’t neglect the importance of remote control! It will save you so much hassle from using button controls on your actual toy and you’ll be able to get off hands-free!
Hollow Strap-ons for Women
It’s also worth mentioning that women can also use hollow strap-ons in the bedroom for hot lesbian sex or intense pegging. These toys can feel great during penetration if you’re too tight or if you can’t handle a big penis. If there’s nothing inside them, they’ll be super bendy. They’ll match their shape to your holes, which is especially useful for extra-tight rear-end adventures. Additionally, you can fit a big vibrator inside and feel the fireworks!
Do
- Choose a quality and comfortable harness with adjustable straps.
- If you’re a beginner, start off with a smaller size.
- The wearer should always know how to put the toy on correctly to avoid any discomfort or awkward ball-pinching.
Don’t
- Don’t grab the largest option you see. Discuss things with your partner and make the decision together!
- If you want to experiment, it’s better to avoid one-piece strap-ons. They won’t allow you to detach the dildo and use a different toy.
- Don’t be shy! If you want something more filling and intense, get honest with your partner and tell him about your secret cravings.
Tips on Using, Cleaning and Storing Your Hollow Strap-Ons
The usage instructions for hollow strap-ons differ from a standard toy, so it’s worth reading the setup steps carefully. Actually, I do because using a strap-on is not as easy as it seems.
How to Put It On Your Guy
The first thing you’ll need to do is secure the strap-on over your guy’s body and his penis.
The correct order is: penis first, strap-on harness second. But be careful: the best way to put your guy’s penis inside is to get him semi-hard. Still, if he’s having problems with ED, they’ll work perfectly without an erection.
The next step is to lube up his penis thoroughly. But remember: most hollow dildos made of silicone or TPE will only work with water-based lube.
Then, when your man slides his penis in, he’ll have to squeeze the dildo to release any extra air. After that, he can slide the harness over his waist and he’ll be good to go! The rest is up to you and your dirty mind… You can use this moment for foreplay – teasing your partner before you’re both ready for the main event.
Clean Your Hollow Strap-on
Sadly, hollow sex toys are some of the most difficult to clean. Still, you’ll have to clean them after each use to stay safe! And no – A quick rinse is not enough for a hollow toy – the internal channel needs thorough cleaning after every use. So stick to my preferred cleaning method:
- Remove the dildo from the harness.
- Use soap and water to wash the dildo internally and externally.
- Leave it out to fully dry.
- Wash the harness by hand or in your washing machine.
- Once the whole kit is dry, you can stash it away. Just use the original box or a sealed, germ-free plastic container.
Hollow Strap-Ons Industry Overview
Before sex toys were available online, they were actually not that popular among the masses. Still, some of our ancient ancestors actually stuffed big stone dildos in their holes more than 30,000 years ago!
And here’s something else you never knew: the sex toy industry had help from an unlikely hero named Ted Marche. He was one of the first inventors of rubber hollow dildos. Strangely enough, his achievements were actually inspired by his love of ventriloquist dummies!
While Marche was a professional ventriloquist who once entertained people like JFK and Dean Martin, he was also an engineer. He used the idea of a prosthetic penis that was developed by another doctor several years earlier. He managed to perfect it to make a hollow rubber dildo that would revolutionize the industry. This kinky ventriloquist turned his idea into a family business and he sold hollow strap-ons to doctors to treat ED as well as to married people who wanted to improve their relationships. A couple of decades later, the online sex toy industry blew up and hollow strap-ons became even more popular!
Nowadays, we are truly spoiled for choice. We can pick from the widest ever range of hollow strap-ons. We can choose from remote-controlled vibrating strap-ons, enormously sized options, and even toys that use AI technology. Plus, it seems that some of the world’s most famous brands are not slowing down. Companies like Doc Johnson, Happy Rabbit, Lovehoney, Fetish Fantasy, King Cock, Tracey Cox and many more are all leading the strap-on business into the future. There’s really no way to tell where things will go next. The only certainty is that hollow strap-ons will become even more lifelike and improved through technology. What a time to be alive!
FAQ
It shouldn’t hurt at all if you pick the correct type for your partner’s body. After all, these strap-ons are ergonomically designed to follow the natural shape of most men’s penises. However, you could still run into problems if you choose a tight or loose hollow dildo. If it’s too tight, it could cause mild discomfort or even skin chafing, so be careful when choosing the size of your silicone hollow strap-on.
Absolutely! This is one of the easiest and safest ways to have sex without condoms. When your boyfriend wears a hollow dildo, he won’t have to use a condom and he’ll be able to come inside it all he wants.
This is a tough question. It could all depend on your partner’s initial size, his sex habits and his self-confidence. There’s a chance you could offend him if you know that he has a problem with his penis size. That’s why you should always talk to him and bring the matter up discreetly. Try to explain why a hollow dildo would be useful for both of you!
Oh yeah! Gay men who want their partners to have bigger and harder penises can most definitely benefit from this toy. It could fulfill many of your and your partner’s anal sex fetishes and also work wonders during foreplay! Plus, it’s one of the safest ways to have anal sex without using condoms.
While these toys are not used as a direct treatment for ED, they can certainly help. If your partner can’t get an erection, these strap-ons will still allow him to have sex and pleasure you. People who suffer from ED can even have strong orgasms while using hollow dildos. However, if your partner has ED, it’s best to consult a doctor first before you try this type of sex toy.
Firstly, you shouldn’t try to force it or freak out. Some hollow dildos can stretch to accommodate your man’s penis size. That’s why you should always use plenty of lube and insert his penis into the dildo slowly. However, your strap-on could feel too tight and uncomfortable if you ended up buying the wrong size. In that case, you should find another toy that suits your partner’s penis better.
Hollow strap-ons require more thorough cleaning than standard toys because of the internal channel. After each use:
1. Detach the dildo from the harness.
2. Flush the hollow channel with warm water, then clean inside and out with mild soap and a bottle brush or your fingers.
3. Rinse thoroughly – soap residue inside the hollow can cause irritation.
4. Leave to air-dry completely before reassembling.
5. Wash the harness by hand or machine separately.
For ejaculating models like the Fetish Fantasy Ejaculating from our list, flush and rinse the reservoir thoroughly and store it empty.
Yes – this is one of the most practical applications of hollow strap-ons. Because the hollow dildo surrounds the wearer’s penis, it reduces direct stimulation and desensitizes slightly, which many men find helps them last significantly longer. Combined with the visual and psychological effect of having a larger device, users with premature ejaculation often report substantially longer sessions. The Fetish Fantasy Unisex Extreme from our list is specifically noted for its ejaculation-delaying effect.
The primary difference is the harness. A hollow strap-on comes with a full harness that fastens around the wearer’s waist and hips, holding the dildo firmly in place regardless of the wearer’s erection status – making it suitable for users with ED. A penis sleeve (also called a penis extender) slides over the shaft without a harness, relying on the wearer’s erection to stay in place. Penis sleeves are simpler and often cheaper, but don’t work for users with ED and may not stay correctly positioned during vigorous use.
Frame it around your shared experience rather than his size. Instead of ‘I want you bigger’, try ‘I read about these toys that add vibration and let us both feel more – can we try one?’ Focus on the mutual benefits: he experiences a larger sensation from inside the toy, you get more stimulation, and the vibrating versions enhance both partners’ pleasure. The Doc Johnson Be Bold from our list is specifically designed as an ED and stamina aid – framing it as a ‘stamina tool’ rather than a size upgrade can help if sensitivity around size is the concern.
