Tired of hearing your partner moan ‘deeper, deeper, please!’, but you’ve run out of dick? Embarrassing, right? Not anymore. Thanks to hollow dildos, you can hit spots you never knew existed, keep your erection longer than usual, and give your partner powerful orgasms.

But with a plethora of options, how do you choose the best? Come with me; I’ll show you HOW. 

After over 4 years of reviewing hollow dongs with my partner, I’ve shared FIVE of my favorites. I particularly fell in love with the Fetish Fantasy Unisex Hard-On for reasons you’re about to discover shortly.

How do We compare Hollow Dildos?

In March 2018, my girlfriend and I embarked on a journey to test some of the best hollow dildos on the market. I must admit that not so many people knew about these toys back then. 

Fast forward four years later, I have tried over 100 different hollow dildos with her, interviewed sexologists and couples, and browsed through thousands of pages on the internet just to learn more about these toys. 

The team of sex toy experts from Sextopedia (which I’m proud to be part of), also conducted a separate study between October 2021 and July 2022 to find out the most important things people considered when choosing a dildo. 

The results from the biggest dildo survey influenced how I ranked these hollow adult toys.

For example, 24% of the over 2468 survey participants revealed that they considered a dildo’s ‘Ability to induce orgasm’ before buying. This explains why ‘Ability to induce orgasms’ had the most weight (40%) in our final score for hollow dildos, as shown in the table below.

Number of Product Reviews56

You can never go wrong with toys from Lovehoney, the best online sex toy shop we’ve reviewed. And if you have erectile dysfunction, the Fetish Fantasy Unisex Hard-on hollow extender comes into play! 

Not only is this relationship-saver hollow dildo ideal for men who want to spice their bedroom up, but it is also perfect for women who want to get busy with a bedroom roleplay scenario.

Fetish Fantasy Unisex Hard-On Hollow Extender

This bad boy is our top pick because of its affordability and great quality, two of the most important qualities we look for when testing dildos. It’s actually the cheapest hollow dildo on this list. That explains the 4.8 rating for ‘Affordability’, the highest rating under this category.

Designed to be firm on the outside, the Fetish Fantasy Unisex Hard-on hollow extender comes with a textured design that offers a defined head and raised veins for the most lifelike stimulative sexual experience. 

No wonder it has the highest number of reviews among the toys I’ll discuss today – 50+ reviews on Lovehoney alone! 

It’s also submersible in water, making it ideal for aquatic fun in the bathtub, pool, etc.

I’ve lost count of the number of times I’ve used this toy in the bathtub with my girl. If I was ever going to lose my job for arriving consistently late, this dong would carry part of the blame. 

The strap-ons are made from adjustable and stretchy nylon that is designed to fit most penis sizes. Plus, this hollow toy is allergen-free, latex-free, and phthalate-free, allowing maximum safety when wearing it.

Not sure how strap-on dildos work? I’ve discussed that in this article.

The Fetish Fantasy Unisex hard-on Hollow Extender has an insertable length of 6 full inches and a circumference of 5.5 inches. Tempting right? Whilst its length is not as generous as the other models, especially the Doc Johnson Silicone Hollow Dildo, it does beat its competitors, price- and performance-wise.

“My wife and I enjoy this toy a lot. It’s a great choice and well worth the money, thanks to the orgasms we’ve experienced together since we bought it. This is probably the most unselfish sex toy I’ve ever used. Everyone cums!”

Reasons to Buy

  • Great for users looking for an affordable yet high-quality hollow dildo 
  • It’s versatile; you can use it for both roleplay and pegging
  • Totally waterproof, making it a great choice for individuals looking for some aquatic fun (try it in the bathtub, you’ll love it!)

Reasons Not to Buy 

  • Although an insertable length of 6 inches and a circumference of 5.5 inches, is quite decent and represents the average penis size per the Sextopedia survey, some users love their toys slightly bigger.

Designed with an adjustable, faux leather harness, the Fetish Fantasy Unisex Extreme Hollow Strap-on Dildo will make your partner scream with pleasure!

The high-quality removable strap-on dildo comes with a reinforced shaft which enables the gents to use it for penis extension. At the same time, the ladies can get their hands busy with some pegging.

Fetish Fantasy Unisex Extreme Hollow Strap-on Dildo

This Hollow strap-on dildo from Fetish Fantasy is lightly padded on one side for ultimate comfort. Plus, it comes with a supple thong back that is comfortable to wear for both men and women.

It is also phthalate-free, but keep in mind that it does contain Latex, unlike its kin – the Fetish Fantasy 6-inch Hard-on.

The toy comes with an irresistible insertable length of 8 inches, a 7-inch inch circumference, and an internal length of 6 inches. It is all fun and pleasure with this one, with a fitted 2.5-inch diameter harness, and a D-ring that allows the dildo to stay firmly in place.

Now you know why I gave it a 4.5 rating out of 5, the second-highest under the ‘Ability to induce orgasm’ and a 4.4 rating overall.

Submersible in water and made of soft plastic – a little lube will let you play your heart out with this firecracker pleaser!

Reasons To Buy

  • This is the toy you need if your partner loves their holes stretched, thanks to the 7-inch circumference. It’s actually tied circumference-wise with the Doc Johnson Silicone Hollow Dildo
  • The 8-inch insertable length also guarantees deep penetration for the ultimate pleasure 
  • The harness adjusts up to 56 inches, which is great for individuals with broader waists 

Reasons Not To Buy

  • The biggest downside of this 10.5-inch monster is that it contains Latex. So if you’re allergic to Latex, keep scrolling.

If you don’t mind spending a few extra $$$ on sex toys just to maintain a healthy and adventurous sex life, the Doc Johnson Silicone justifies its 4.5 overall rating out of 5, and for many reasons.

Doc Johnson Silicone Hollow Remote Control Strap-on set

First of all, Doc Johnson never disappoints when it comes to creating high-quality sex toys. The American sex toy company has been in business for over 40 years, creating some of the best-handcrafted toys I’ve used with my partner. 

This premium hollow dildo is actually one of my girlfriend’s all-time favorite hollow dongs. I remember she couldn’t stop squirting the first time I brought it home. I guess it’s because of the intense vibrations, wide circumference, and generous length. 

“I love the fact that this toy has excellent quality and also offers great value for money. It really hits spots I can’t and makes her squeal with delight.”

I’ve never read a more relatable review in my life. 

Envisioned to satisfy one’s wildest sexual cravings, the Doc Johnson Silicone Hollow Remote Control Strap-on set offers a full 9-inch length at your disposal. It is equipped with a wide elastic waistband that promises a comfortable and secure fit, and at the same time, it is super easy to put on, and clean.

Empowered with remote control, the hollow dildo from Doc Johnson boasts 3 speeds and 7 different vibration patterns to tickle your fancy. The toy is also phthalate-free and body-friendly, with an insertable length of 8 inches and a full length of 9 inches.

The Doc Johnson Silicone Hollow Remote Control Strap-on set gets in there and knows the deepest depths of your erotic pleasure.

What’s more, the toy’s dong is firm, which makes this silicone hollow dildo ideal for pegging or other penetrative pleasurable play.

Reasons To Buy

  • The generous length and girth are all you need to pound your partner’s walls and give them explosive orgasms 
  • It’s actually easy to clean, accounting for 10% of the decision-making factors I considered when ranking these toys 
  • It’s made from silicone, one of the safest dildo materials out there 

Reasons Not To Buy

  • The Doc Johnson has a saltier price than the first two, which explains the 3.9 rating for ‘Affordability, the lowest among the toys I’ve reviewed so far. But despite that, it justifies the price tag with its remote control features, as well as its impressive length that gets you off every time!

Equipped with 3 different vibration speeds, this vibration dildo allows you to experiment and find the one that makes you scream the most. It has a flared base that promises safety and fun at the same time.

The Sportsheets Lennox Hollow Vibrating Silicone Dildo is made from silicone and is compatible with water-based lubricants. Simply coat some lube on the dildo, find your spot and pace – and get riding!

It was actually difficult to find a single thing my girl doesn’t like about this toy performance-wise, so I checked out reviews on Lovehoney to find out what other users think about it. 

“I really like pretty much everything about this bad boy. I particularly love that it allowed us to attempt something new. It’s a bit pricey, though, but the quality is unbelievable and the orgasms indescribable.” 

Reasons To Buy

  • The curve, the length, the circumference, the vibrations – this toy truly understands the assignment
  • Features a sturdy base, which is great for anal penetration
  • The vibrations concentrate in the ‘head’, making it even more pleasurable during penetration, especially when it massages the G or P spot

Reasons Not to Buy

  • Some users have complained that it’s not the quietest toy in the room. But if that’s the price to pay for consecutive orgasms, so be it.

Designed for gents looking for something more exciting in the bedroom, the Doc Johnson Strappy Hollow Penis Extender is here to give you 7 inches of space to work with.

Made from a Sil-A-Gel material, this Hollow Penis Extender is latex-free, phthalate-free, anti-bacterial, non-toxic, and most importantly, body-friendly.

Doc Johnson Strappy Hollow Penis Extender

It’s crazy to think that this was actually the first-ever hollow dildo I tried with my girlfriend. We had just started experimenting with sex toys and didn’t want to go full bazooka on day one.

Its size was perfect for our beginner adventures. 

Besides, I was struggling with premature ejaculation at the time, and I badly needed a savior.

And based on its reviews online, I guess I’m not the only one who’s witnessed the ways of this savior.

This beginner-friendly hollow phallus comes with a bulbed head and smooth shaft, which enables not just pleasurable external stimulation but also internet caressing as well. Its circumference stands at 6 inches, whereas its internal length is 6.5 inches.

“My wife loves the fact that I last longer in bed using this hollow companion. I no longer have to worry about premature ejaculation or the feeling of disappointment that tormented our sex lives for years. The best part of it is that I still remove it to finish naturally (of course, after my wife cums). It’s a win-win with this one!”

Reasons To Buy

  • The simple design makes it super easy to clean, which justifies the 4.7 out of 5 rating for ‘Easy to clean’
  • Features a bulbed head and smooth shaft for increased pleasure
  • Has a raised ridge at the base for increased external stimulation 

Reasons Not To Buy

  • Some users have complained that it feels too hard. My girlfriend felt that too in the beginning, but then things changed when we added more lube.

What is a Hollow Dildo?

A hollow dildo is very similar to a regular dildo, design-wise. A hollow dildo looks like an actual penis and makes for a lifelike feel and sensation. The only difference between the two is that hollow dildos have empty cylinders on the inside – meaning, they leave designated room for your dick to fill in.

The hollow dildos can be useful for those struggling with semi-erect penises. What’s best, you can even use it with a flaccid penis. These sex toys are made to add some length and girth to your penis size.

Nowadays, hollow dildos come in different designs – from regular hollow strap-ons that can be firmly attached to your waist to strapless and even vibrating hollow dildos that take care of your orgasm with multiple speeds and patterns.

Choosing the Best Hollow Strap on Dildo for You

Finding a hollow dildo that will suit you can be a challenging task. There are many brands of strap-on hollow dildos on the market today, some of good quality and some – well, not as much.

Before going hunting for the best strap-on hollow dildos for you, here are the quality factors to consider.


To find out the ideal strap-on hollow dildo size you should buy, you first need to start taking some measurements. Measure your penis in length and girth and then compare the measurements with the ones of the hollow dildo of interest.

Make sure to always leave some room in the hollow dildo – after all, you should dive into the experience with utter comfort.

Material and Shape

A hollow dildo can come in many shapes and materials. Most hollow strap-on dildos are designed to look like a real penis, with a natural appearance and unique features.

However, when it comes to material and shape, no two hollow dildos are the same.  

Unsafe & Safe Sex Toy Materials | Read More

From textured veins to bumps and a realistically-looking head – most hollow dildos are curved to a certain angle, which makes it easier to hit all your hotspots. Material-wise, most hollow dildos are made from silicone.

Fun fact: circa 90% of the sex toys you can find on the market today are made from silicone. This is because silicon makes sex toys, including all types of dildos body-safe, soft and firm at the same time.

Robert Thomas – Sexologist

Plus, silicone is a very durable material, works great with water-based lube, and is light enough to eliminate all pressure made against your sausage.

Finally, silicone can be easily cleaned with soap and warm water. Whereas, in terms of shape, it’s best to again, choose one that fits your penis just enough so it both moves freely and sets a raunchy pace.

How to Use a Hollow Strap-on dildo?

When using a hollow strap-on dildo, you have to first start by putting the harness on. Even though it looks complicated right from the start, it is not.

Every hollow strap-on dildo comes with buckles for each of your legs, and you only need to step inside them. Next, you need to adjust the straps to the size of your waist and treasures. The hard part is done, now it’s time to get into action!

One more thing you should consider before buying your hollow dildo is to make sure that your penis can fit inside the cylinder. There are different sizes of hollow dildos, so correct measurements of your penis will help with buying the right size of hollow dildo.

Some hollow dildos come equipped with ball cups so you can fit your testicles inside as well. If the hollow strap-on dildo comes with ball cups, your penis goes in there first and then your sack.

In case you have difficulties putting your penis inside the hollow dildo – apply some water-based lubricant inside the toy itself and give it another shot.

Cleaning the hollow dildo is made quite easy – use soap and water to remove all traces of lube and body fluids and ensure you store it in a safe place, ideally in the toy’s original package.

Hollow Strap Ons: Summary

Out of all sex toys out there, hollow dildos are the ones that simultaneously have both partners’ interests and pleasure in mind. It’s also a great sex toy for gents that are suffering from erectile dysfunction or those who need the extra push to a full erection. And, guys can use these sex toys to add some length to their real penis.

A strap-on hollow dildo can be used by women as well, depending on whether some pegging is to take place.

All in all, no matter which one you decide on for your passion-filled trysts, remember that water-based lube is your best friend here, as is the right fit.

As for the rest, trust your imagination and bedroom creativity to throw you in the lustful spotlight and make a proper lover out of you! Just to remind you, my favorite is the Fetish Fantasy Unisex Hard-On.
