How We Tested Hollow Strap Ons

Anyone can make a “Best of” list, but when you’re planning on spending your hard-earned money, it’s important to make sure that the list you’re reading is backed up by research!

Whether your budget is large, small, or somewhere in the middle, you’ll be able to find the best-value toy for yourself using this system! Our standardized rating system allows us to remain as neutral as possible, which means you won’t have to deal with any brand bias while picking out a product.

What Size Hollow Strap On Should You Get?

When shopping for a hollow strap-on, there are two things you’ll want to consider: the size of your penis and your partner’s preferred dildo size.

It’s important that your penis can still fit inside of the strap-on even when erect. Beyond that, sizing is up to your partner!

They will likely have an idea of how big they would like to go, but if not, then they can measure the depth of their vagina using a dildo & the maximum width of their vagina using their fingers. After the maximum number of fingers have been inserted, use a tape measure to measure the maximum circumference achieved.

With these measurements in mind, you’ll have a much easier time shopping for your new toy!

Whether you are looking for a large hollow strap-on for maximum impact or something a little smaller, we’ve got something for you! And if you want a range of sizes to suit your mood, be sure to check out the best for beginners winner!

A Closer Look at the Doc Johnson Hollow Strap-On Set

Now you can have a shaft that’s ready to go whenever and can really go all night!

Both the hollow non-phallic dildo and the harness of this strap-on set from Doc Johnson are made of smooth, luxurious silicone that will feel fantastic for both you and your partner, especially as it warms up during the heat of the action.

The seven-inch dildo slips over your penis, and the bulbed end enhances the stimulation, allowing you to pleasure your partner for as long as you want.

Although the hollow shaft is designed to accommodate a penis, this toy can be worn by anyone, and the shaft is stiff enough to use vaginally and anally.

Pros

  • Silicone shaft and harness
  • Waterproof
  • Bulbed head
  • Comfortable

Cons

  • Can be tricky to use at first
  • Might not fit larger penises

My verdict

This high-quality hollow strap-on is our test winner of this round-up review because it scores highly on form, functionality, and of course, fun!

The harness and strap-on are extremely comfortable for the wearer and still provide a good level of stimulation. The receiver also gets a great level of stimulation from the soft but firm shaft and sculpted head.

The price is fantastic for a hollow silicone strap-on with so many different uses. The dildo can be worn by a wearer with a penis or vagina, can be used for vaginal or anal penetration, and can even be used for some wet and wild fun in the shower!

Buy, if you...

  1. want an affordable product with good quality materials
  2. want a non-realistic hollow strap-on

Don't buy, if you...

  1. are extremely large, down there
  2. prefer something slightly textured

A Closer Look at the Doc Johnson Hollow Strap-On 4-piece Kit

The goldilocks of hollow strap-ons! Everyone can find something ‘just right’ in this strap-on set that contains a whopping three different silicone dildos.

The three different size dildos are all made from soft but firm silicone and feature a bulbed tip to up the stimulation for your partner.

The choice of sizes makes this hollow strap-on one that can be used in many different ways and can still keep things exciting over time.

You still get to enjoy the sensation through the silicone shaft with the added bonus of being able to pleasure your partner for as long they desire!

Pros

  • Three changeable dildos
  • Silicone dildos and harness
  • Waterproof
  • Bulbed shafts

Cons

  • Hollow canal might not fit larger penises
  • Can be tricky to use at first

My verdict

This comprehensive kit has pretty much everything you need to explore different types of strap-on fun. You really are spoilt for choice!

The hollow strap-on can be worn over a penis, allowing you to explore new record-length sessions or add some extra size. Alternatively, it can be worn by someone with a vagina, and the shafts are rigid enough for anal penetration, making this a perfect set for pegging, especially with the smaller-sized dildo.

Having three different sizes also means you can keep experimenting and moving onto the next size as you get more comfortable with the set.

The price is great for such a versatile and well-made toy that brings endless opportunities to spice up sex with your partner!

Buy, if you...

  1. have not tried sticking your penis inside a hollow dildo or strap-on
  2. want multiple different sizes and options

Don't buy, if you...

  1. don't want to overpay for quality and ease of use

A Closer Look at the Lovehoney Perfect Partner Unisex Hollow Strap-On 6 Inch

A realistic strap-on that can go for an unreal amount of time! This hollow strap-on from Lovehoney is sure to fulfill you and your partner’s fantasy for some all-night fun!

The comfortable elasticated harness fits most sizes and the thick elastic straps make it comfortable to wear even for long sessions.

Your partner will love the smooth shaft with realistic details, such as raised veins and a sculpted head that add stimulation with each movement you make.

Pros

  • Realistic details
  • Waterproof
  • Comfortable harness
  • Great size

Cons

  • PVC is porous
  • Can have a plastic smell
  • Can be too hard for some
  • Won't fit larger penises

My verdict

This realistic hollow strap-on has a great size and feel and can allow you and your partner to experience longer-lasting sex. The textural details add a layer of stimulation, and the design is great if you want to keep it lifelike.

Although this is a unisex toy, the hollow shaft can bend when worn by someone without a penis, so this strap-on is best when worn over a penis. If you are looking for a strap-on for wearers with a vagina, it’s better to go for a more hollow solid strap-on or non-hollow strap-on.

You can use this hollow strap-on for vaginal and anal penetration, and you can use it in the shower for some extra steamy, slippery strap-on sex.

The low price makes this a great option if you want to try out a hollow strap-on without investing in a pricier option. However, being made of PVC, a porous material, this strap-on cannot be fully sterilized and should be used with a condom for penetrative use. This also means it can have a plastic smell, especially when it’s new.

Buy, if you...

  1. want a super cheap hollow strap-on
  2. enjoy a realistic design
  3. need an adjustable harness

Don't buy, if you...

  1. want high quality materials

A Closer Look at the Lovehoney Perfect Partner Vibrating Strap-On

This vibrating hollow strap-on is designed so that it can be worn by anyone. Wearers with a penis can slip inside the hollow cavern and enjoy the delicious vibrations that pulse through the shaft.

The partner being penetrated gets the pleasure of the vibrations as well as the intense full feeling from the thick, long, textured shaft!

The three speeds and 7 patterns of vibration can be switched up using the wired remote, which can be used by either partner or slipped into the waistband when not in use.

Pros

  • Vibrating
  • 3 colours available
  • Remote controlled
  • Long, thick shaft

Cons

  • Inner canal too small for larger penises
  • Harness doesn't fit larger sizes
  • PVC is porous
  • Battery powered

BuzzyBuzzy
What it is: Buzzy vibrators have a high frequency that stimulates the surface (like a high pitch).
RumblyRumbly
What it is: Rumbly vibrators have low-frequency vibrations that stimulate deeper into the tissue (like the bass in music).

My verdict

The best thing about this hollow strap on is that it is unisex! It can be worn over a vagina or the hollow canal can accommodate a penis and both partners get to enjoy the vibrations.

While the canal is designed to fit most penises, if you have a larger-sized penis (more than 6 inches long and 1.5 inches wide when erect), the canal will be too small for you.

The shaft is large, so perfect for vaginal penetration or people who enjoy larger anal toys.

This is a very reasonably priced vibrating strap-on, but the shaft is made of PVC which cannot be completely cleaned as it is porous and it is battery powered. This would be a good option to try this type of toy for the first time.

Buy, if you...

  1. love internal vibrations during penetration
  2. enjoy vibrations around your shaft
  3. want the vibrations to be optional

Don't buy, if you...

  1. don't want PVC in your products
  2. want a wireless vibrating feature

A Closer Look at the Fetish Fantasy Ejaculating Strap-On

This is about as real as it gets! Not only does this hollow strap-on feature lifelike balls and textural details, it even ejaculates at your command!

7.5 inches long and with veined details, this impressive shaft slips over your penis and allows you to go all day and night if you want to.

Pair this ejaculating hollow strap on with some special cum style lube for some explosive loving!

Fully waterproof and featuring a comfortable, stable harness you will get plenty of fun out of this strap-on set.

Pros

  • Ejaculating
  • Realistic balls
  • Textural details
  • Comfortable harness

Cons

  • PVC is porous
  • Canal is too small for larger penises

My verdict

There’s no doubt that this realistic, ejaculating hollow dildo can lead to some pretty intense orgasms, and it’s way less fiddly than other options. All it takes is an intuitive squeeze to set of the spunk that adds an extra to Oh to your partner’s orgasm, especially when you time it just right.

As the wearer, whether you have a penis or not, the lifelike shaft and ability to ejaculate keep things as real as they can get, and the ability to ejaculate (wherever you choose to do it) add a whole new level to the experience.

This is a reasonable price for a hollow strap-on with this level of functionality, but the toy is made from PVC which is porous and cannot be fully sterilized.

Buy, if you...

  1. have erectile dysfunction and want the feeling of cumming again
  2. love the realistic look

Don't buy, if you...

  1. feel that it would be to large

This big boy hollow strap-on means business. The hefty 8-inch long dildo with a might 7-inch girth will leave you completely full and weak at the knees. It is designed to hit sweet spots you didn’t even know existed, resulting in some immense orgasmic power.

Easy to use, you simply step into the lightly padded harness and slip the shaft over your penis (if you are a penis owner), and you are good to go for some mammoth sessions that will leave you and your partner happily exhausted.

The added texture from the raised veins creates tantalizing sensations with each move, and your partner will love the added stamina!

This hollow strap-on is waterproof and features a fully adjustable harness in sleek black faux leather for a more luxurious look and feel

Pros

  • Extra large dildo
  • Realistic details
  • Padded harness
  • Waterproof

Cons

  • Made from porous soft plastic
  • Limited positions due to the downward curve
  • Canal is quite rigid
  • Strap position can be awkward

My verdict

So as you can guess, this is an advanced toy and is best for the size kings and queens out there looking for something big and bold. To get the best experience, make sure to use plenty of lube and warm up properly to make sure you are fully aroused.

While the size and texture really do lead to some intense sensations, the downwards curve of the shaft limits the number of positions that you enjoy with strap-on.

The faux leather straps have a more luxurious feel than the usual elastic waistbands. If the wearer has a penis, the crotch strap sits to one side of the testicles, which can feel a little awkward.

While the price is pretty good for such a sizeable toy complete with a good harness, the materials used in the dildo aren’t the best. Being made from soft plastic means that this toy is porous and can’t be fully cleaned, making it less safe than a silicone option.

Buy, if you...

  1. enjoy extreme fulfillment
  2. have a larger penis
  3. like heavier hollow strap-ons

Don't buy, if you...

  1. are a complete beginner to large dildos

A Closer Look at the King Cock 10 Inch Hollow Strap On Penis Extension With Suspender Harness

The King Cock 10 Inch Hollow Strap On is a great device for transforming your dong into an impressive 10 inch monstrosity!

With an extremely realistic design with stimulating textures in the shape of bulging veins and a pronounced head and lifelike balls, this is great for anyone with ED who wants to indulge in the look and feel of some large, lifelike arousal.

The suspender-style harness will provide you with extra stability during powerful thrusts. It is also easy to use and fully adjustable!

Pros

  • Suspender harness for extra stability
  • Large strap-on for intense penetration
  • Fully adjustable harness

Cons

  • Made from porous PVC

My verdict

This big guy is best suited for anyone who wants to try having this much length and girth to penetrate their partner with. If your partner loves being strethed out and fille up and is longing for some super-sized pounding, then you can make their dreams come true with the King Cock! Keep in mind that the penis sleeve itself is made of porous PVC, so it is not suitable to use internally without a condom, as dirt and bacteria can get trapped in microscopic holes in the surface of the shaft over time.

Buy, if you...

  1. really enjoy a a large hollow strap-on
  2. want a harness with more stability

Don't buy, if you...

  1. prefer something smaller
  2. don't like a realistic texture

Types of Hollow Strap-On

The main characteristic of hollow strap-ons is that they all have a hollow internal chamber. This means that most hollow strap-ons are unisex and can be worn by a person with a vagina or a penis, making it a super-inclusive toy that everyone can enjoy! This is also why you might hear them called male strap-ons.

Variety is the spice of life, so as always, there are some different options to choose from. Check out the three main types of hollow strap-on below.

Why Is the Male Strap-on Dildo Hollow?

Although most hollow strap-ons are designed to be unisex, one of the main advantages, compared to regular strap-on dildos, is that the hollow compartment means it can be worn over a penis. This makes hollow strap-ons the best strap-on option for penis owners!

Video guide

There are many reasons you might want to wear a hollow strap-on over your penis from health reasons to added functionality! Here are just a few reasons you might want to try out a hollow strap-on:

  • Erectile dysfunction – you can still have sex with your partner even when you can’t get an erection.
  • Premature ejaculation – you can continue to pleasure your partner after you have ejaculated
  • To give you superhuman stamina, even if you don’t have any problems with your erections
  • To experiment with different sizes and textures with your partner
  • To add new sensations, such as vibrations for you and your partner
  • To try out double penetration

How to Choose the Right Size Hollow Strap-On?

There are things to consider size-wise when you are choosing your new hollow strap-on. Firstly, that the hollow canal fits over your penis, if you have one, and secondly, that the dildo is a good size for your partner.

Internal canal size

Internal canal size

Internal canal size
Internal canal sizeYouTube play button

As the internal canal should slip comfortably over your penis, it’s important to make sure there you can fit inside it. After all, a cramped cock won’t be comfortable for very long!

Firstly, you need the diameter of your erect penis. You can do this by measuring around your erect penis at the widest part to get the circumference. Then, you can divide the circumference by 3.14 (pi or π), and this will give you the diameter.

Dildo size

The second consideration involves choosing a suitable size dildo for your partner. This will depend on several things, including, experience with dildos, general size preferences, and whether the dildo will be used for vaginal or anal penetration. This handy video from a sex toy educator goes into more detail about how to get it just right!

Types of Hollow Strap On

There are a few different types of hollow strap-ons. You’ll want to compare the available options before making a decision. Here are the options on the menu!

  • Interchangeable dildos – If you want to use multiple dildos with your strap on then having an interchangeable model is key! These allow you to switch out the dildo for your strap-on, opening up a world of options in the bedroom.
  • Vibrating – As the name implies, these strap-ons add vibrations into the mix for surreal sensations!
  • Double Penetration – Depending on the toy in question, these DP strap-ons may utilize the wearer’s penis or two dildos to achieve the desired results. Either way, double penetration means twice the fun.

Hollow Strap Ons VS Penis Sleeves/Extenders

Although they serve a similar function, there actually is a difference between hollow strap-ons and penis sleeves/extenders!

  • Hollow strap-ons are devices that are hollow inside, allowing you to fit your erect, semi-erect, or even flaccid penis inside, and they are held in place by a harness. These can be especially useful for men who suffer from erectile dysfunction (ED), as you can still enjoy penetrative sex without a rock-hard erection. Of course, they can also be enjoyed by women as well!
  • Penis sleeves/extenders, while similar, are designed to fit snug over an erect penis. Wearing a penis sleeve will increase your girth and length, but isn’t very helpful if you can’t maintain an erection (or lack a penis).

Materials

Whether you’re shopping for a realistic hollow strap-on, a vibrating hollow strap-on, or just for strap-ons in general, you’ll quickly notice that there are a small variety of materials to choose from.

Unfortunately, not every material is created equally, so you’ll want to stick to high-quality materials for the best experience. Rather than selecting a porous hollow jelly strap-on (which can harbor bacteria and can’t be sterilized), we recommend sticking to a non-porous material like silicone.

Assuming they don’t contain any internal electronic elements, these materials can be fully sterilized for a safer sexual experience!

Strap-On Penis Extensions and Erectile Dysfunction

A strap on penis extension is not just made to provide you with extra girth and length. A different use is as well to enhance your erection. If you suffer any disease related to your erection like Erectile Dysfunction a strap on penis extension might work for you. This is a different alternative from the many that can be found to help you recover your sexual life. Below I give you some tips that might be helpful for you.

Find the right one for you

The first thing you might consider is to find the right strap on penis extension for you. There are different types and depending on what is your situation you might want to buy the one that will suits you the best. Think about how bad is your problem and how the flexibility, materials, and other features can help you to have the sex life you had before.

How a strap on penis extension can help me?

Well, a strap on penis extension will provide you with a hard erected fake penis that will replace the function of your own penis. With a strap on penis extension, you won’t have to worry about how long you are going to last hard. Also, your partner will love the girth and the length. Bear in mind, before you get one, to ask your partner the size and girth, in this way both are going to enjoy a lot.

So how do I use it?

So far, depending on what kind of strap you got, almost every single option is the same when comes to using it under these circumstances. Before you wear the strap on be sure to lube the inside part where your penis is going to be. Even though you won’t have an erection, this will be the feel better in case you get wild, the lube will help you to avoid any uncomfortable feeling. Also, you have to lube the other side, the one that will be inside your partner, to provide your partner with pleasure and avoid the same kind of feeling you might have inside if you don’t lube it at all (or enough). So lube outside and inside, wear it, tight it up with the straps, and get ready to have fun!

Combine and win (more)

One good point about a strap on penis extension is that you can use it among other sex toys as well. If you own a penis pump (or you are planning one) you can use it first before wearing the strap on penis extension, get a cock ring to keep the blood all over your member, then wear the strap on penis extension and enjoy! Vibrators, wand sex toys, or even dildos can work very well along with a strap on penis extension. Basically now, the limit is your imagination.

What's the Difference Between a Hollow Strap-On and a Penis Extension?

Although both of these items fit over your penis and will provide your partner with extra stimulation, the option you should choose actually depends on your penis.

How so? Well, hollow strap-ons are essentially hollow dildos. The wearer’s penis is inserted inside of the hollow strap-on, which is then used to penetrate their partner.

A penis extension works the same way, but unlike hollow strap-ons, these cock sleeves are designed specifically to be used with erect penises.

They lack any type of rigidity or support, instead relying on the user’s erection to maintain their form.

Hollow strap-ons, on the other hand, are rigid toys that can be used with or without an erection, making them ideal for men who suffer from ED. Furthermore, hollow penis extension strap on toys don’t even require a penis: females can use them as well! Despite these fundamental differences, both types of toys offer a lot of variety in design, with both unrealistic and real feel strap on penis extension toys being widely available.

How to Use a Hollow Strap-On?

As hollow strap-ons are designed to be worn over a penis, these instructions detail how to do just that. But no problem if you are using a hollow strap-on without a penis, simply skip the second step!

 How to Use a Hollow Strap-On?

Getting into your harness

Getting into your harness

The first step is getting into the harness. The two main styles are the thong, which has one crotch strap that goes between the legs, and the jockstrap, which has two straps that join to the waistband at the back. Start by getting into your harness and tightening the straps so the harness sits snugly against your body.

 How to Use a Hollow Strap-On?

Fitting the canal over your penis

Fitting the canal over your penis

Next, you can lube up your penis and in the inner canal and slip the hollow strap-on over your penis. You will need to loosen one side of the harness to do this, so remember to tighten it again when you are securely in place. You might find that being in a semi-erect state makes it easy for you to enter the inner canal. This process can take some practice, so you might want to practice this solo beforehand.
