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!
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!
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).
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!
FAQ
What is a hollow strap-on?
Hollow strap-on dildos are usually worn in a harness and have a hollow canal, meaning they can be worn over a penis. They are unisex and can also be worn over a vagina, making them great for pegging and giving you more ways to play. Hollow strap-ons are popular with people who have erectile dysfunction, as they can be used with a flaccid or erect penis.

Hollow strap-ons fit snug to your penis and are held firmly in place using an adjustable harness. They are perfect for all types of penetrative play and come in a range of designs, so whether you prefer a realistic design or not, vibrations, or some added texture, there's something out there for you!

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.

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.


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.
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.


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.
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.


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.
Fetish Fantasy Unisex Extreme Strap-On

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


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.
Fetish Fantasy 7 Inch Hollow Strap-On With Balls In Brown

This hollow strap-on fits over your own appendage and gives you the ability to please your partner with the added size and all-night-long stamina.
The dildo features raised veins, a sculpted head, and realistic balls for a lifelike look and feel that can take your partner to new heights of pleasure.
The adjustable harness has thick, wide, elastic straps that are comfortable to wear and leave your hands free for all kinds of fun. The set is also waterproof, making it perfect for some shower action.


This realistic hollow strap-on features some great details. The raised veins and lifelike head add sensation as the shaft moves, and the gentle curve can hit the right places when you get the right position.
The set is well priced, but the main downside is that it is made from PVC, which cannot be fully sterilized due to its porosity. This is a good option if you want to try out a large hollow strap-on before investing in a silicone model, which is safer but does tend to be more expensive.
