Hollow Strap On Dildo

I think hollow strap-ons have a bad reputation with some people. Either they don’t fit, they’re too big or too small, or they’re just not fun to use. 

Personally, I like hollow strap-ons even though my penis is pretty healthy. I like waving around a big vibrating fantasy-size cock every now and again. And I know they can be a real sex lifesaver for men suffering from all kinds of performance issues. 

And then I realized. Maybe those people who don’t like them just haven’t found the right one yet. 

If that sounds like you, then read on! One of the dildos on this list could be your Holey grail. 

Let’s check out the Top 3 real quick below and then move on to the rest, along with some useful info about choosing the right strap-on for you.

Marketed as a solution to ED, the RX sleeves come in multiple different sizes and shapes, from average size to intimidating.

Each sleeve is unique — they’re based on the same molds but no two RX sleeves come out exactly the same!

All of the RX sleeves come with a belt harness that’s a cinch to use (get it? Cinch?) and are fitted through a testicle loop. 

They’re super realistic and incredibly well made, with a price to match. They’re more like prosthetic limbs than sex toys!

If you suffer from ED and want the very best product to get your mojo back, the RX sleeve is worth taking a look at.

Circumference:

Color:

Waist Size:

  • Great value for money
  • Wide base for a secure hold
  • Quality silicone dildo
  • Only one size O-ring, so the harness won’t fit every dildo
  • Harness feels cheap

If you had told me it was possible to find a decent-quality hollow strap-on for $39, I would have laughed.

Until I discovered this beauty from CalExotics. It’s 7 inches of non-porous silicone with a stretchy harness that should fit almost anyone. 

This thing really adds some length and girth with a 3-inch solid head leaving about 3.5 inches of internal length for you to fill. 

It’s comfortable and secure – no matter how hard you pound it shouldn’t slip out or move around awkwardly, which for a cheap extender is awesome. 

Honestly, at this price, it’s hard to come up with many drawbacks to this extender. The harness isn’t the best build quality and there’s only one O-ring. 

But then again, it’s still better than I would have expected. It really is the perfect extender for beginners.

Material:
Silicone
Insertable Length:
7”, 7.5”, 8”
Circumference:
6”, 7”
Color:
Black
Waist Size:
28” to 48”
  • Nice vibrations
  • 3 different size dildos included
  • Suitable for DP
  • Might be too big for some couples
  • Different sizes aren’t that different

This is the perfect upgrade for couples who know they like penis extenders and want the best. 

There are three different sizes to try out which I think of as Pretty Big, Big, and Very Big. 

All of the dildos are made of premium quality silicone so they’re non-porous, totally body safe and easy to clean. All you have to do is wash them in soapy water.

It’s even good for double penetration as there is a sizeable hole underneath the dildo. Not to mention the dildos are stiff enough to use on their own. 

There’s also a rechargeable bullet vibrator built into the harness, which feels great for both partners during use. It’s strong enough that you can both feel it, but not so strong that it distracts from sex or makes you cum too fast. 

A great choice all around.

Circumference:

Color:

Waist Size:

  • Works well for STP
  • Comfortable enough to use all-day
  • Harness not included

It’s nice and soft, realistic looking, and functions very well as a stand-to-pee device (I’m told). 

Those veins are nice and convincing to hold, too. Actually the attention to detail all over is great. 

The silicone material warms quickly to body temperature, making it feel much more real than something made of plastic. 

It’s light, comfortable, hygienic and cheap. As far as packers go, you could do a lot worse. 

This packer doesn’t come with a harness, so you’ll have to get a boxer harness to use it if you don’t have one already.

5. Fetish Fantasy Extreme 

Price:
$$
Material:
Plastic
Insertable Length:
8”
Circumference:
7”
Color:
Black, Flesh Pink
Waist Size:
16″ to 56”
  • Easy to put on and secure fit
  • Well-made harness
  • Great for size lovers
  • Needs a lot of lube
  • Contains latex

Hope you like ‘em big… Because this thing will fill your partner up and stretch them out!

The faux leather harness is a good one: It’s very easy to get on and off quickly, holds in place and looks good while you’re wearing it. 

The Fetish Fantasy Extreme is hard enough to be used as a penis extender or as a strap-on for pegging, which is a nice touch of versatility. 

The plastic is harder than some of the softer silicone dildos, which might not be to everyone’s taste. With the hard plastic hollow core, it’s definitely firmer than a real erect penis. 

If you don’t like the hard plastic core of the dildo you can always remove it and just use the softer outer layer, which feels really nice. 

One thing to remember before you buy: this thing is BIG. Like, really big. 8 inches long is one thing, but 7 inches in circumference?

Don’t let your eyes get bigger than your stomach. Or holes.

Oh yeah, and the plastic contains latex. So make sure no one is allergic!

Best vibrating hollow strap-on

6. Lovehoney Perfect Partner

Price:
$
Material:
PVC
Length:
8”
Internal Length:
6”
Circumference:
6.25”
Color:
Purple, Black, Flesh Pink
Waist Size:
38”
  • Sturdy but not too hard
  • Doubles as a pegging toy (if you can take the size!)
  • Affordable
  • Big and no choice of size
  • Smallish waist size limit

If you want a penis extender, you want your enhanced to look good, right? 

This is the toy for you. This is a pretty strap-on. It’s long, thick, has nice rippling and the purple color especially is gorgeous! 

It has a powerful vibrator in the tip which mainly stimulates the receiver. That said, it’s strong enough to vibrate down the shaft and tingle the penis very nicely. 

Shame that it’s battery operated and not rechargeable, but at this price that’s hardly a complaint. 

It’s thick so any penis around average size should fit inside easily. 

Plus, it’s rigid enough to use as a pegging toy — although it’s so thick that you might struggle unless you’re already a veteran of butt stuff. 


7. Blush Dr. Skin Hollow Strap-On

PRICE:
$
MATERIAL:
PVC
LENGTH:
7”
CIRCUMFERENCE:
5.49”
COLOR:
Black, Flesh Pink
WAIST SIZE:
40”
  • Super comfortable wide-strap harness
  • Nice textured shaft
  • Very firm, but with some flexibility
  • Might be too rigid for some people
  • PVC is porous

If you’re into SIZE but don’t want to go overboard, this hollow strap-on is generous without being overwhelming.

It’s made from phthalate-free PVC, which makes for a very rigid dildo

However, some people do find it to be too hard. 

If you suffer from any mobility issues, the firmness of this dildo can help keep it in place without much need for thrusting.

For the wearer, the harness is a dream. 

The wide hip strap is incredibly comfortable and secure. And even for average-sized penises, the internal canal doesn’t feel restrictive.

The biggest downside is that PVC is a porous material. 

If it’s not cleaned properly, it can harbor bacteria. 

Use a condom if you plan on switching between anal and vaginal penetration.


8. Fetish Fantasy 7.5 Inch Ejaculating Strap-On

PRICE:
$$
MATERIAL:
PVC
LENGTH:
7.5”
CIRCUMFERENCE:
6.25”
COLOR:
Flesh Pink
WAIST SIZE:
Up to 52”
  • Highly adjustable harness
  • Comfortable wide straps
  • Can be used with any body-safe ‘ejaculate’
  • Very realistic
  • Fits smaller penis sizes
  • Only comes in one color
  • PVC is porous
  • Can collapse slightly on wearers who don’t have a penis

If you’re going for a super-realistic experience, this toy is the whole package (pun intended). 

The realistic design sells the idea that this is your own cock (as long as you have pale skin), and the ejaculating feature means you and your partner will get the full experience. 

You simply squeeze the end of the cock to shoot your load wherever you want.

This is specifically designed for people with penises below the average. 

It will be most comfortable if your erect length is around the 4-inch mark. 

However, if you don’t have a penis, this might not work well for you. 

The hollow base means that, unless you have something filling the shaft, it tends to collapse in on itself with thrusting.


9. Doc Johnson Body Extensions Be Daring Hollow Strap-On

PRICE:
$$$
MATERIAL:
Silicone
LENGTH:
Small: 7”, Medium: 7.5”, Large: 8”
CIRCUMFERENCE:
Small: 6”, Medium: 6”, Large: 7”
COLOR:
Black
WAIST SIZE:
28”- 48”
  • High-quality materials
  • Super comfortable harness
  • Three dildo sizes
  • Firm enough for pegging
  • Only comes in one color
  • Expensive

There’s so much to love about this strap-on set. 

Firstly, it’s made from silicone, which means it’s completely body-safe and easy to clean.

Secondly, the three interchangeable dildos give you an array of choices. 

This is great if the receiver is size training, if you have multiple partners with different preferences, or if you want the smaller options for pegging or anal sex

The harness is very well made and super sturdy. It’s comfortable and requires no adjustments during sex, so you can concentrate on enjoying yourself.

If you have the cash to splash and want the deluxe kit, you can’t look past this option.


10. King Cock Hollow Dildo Strap On

PRICE:
$$
MATERIAL:
PVC, body-safe polymer
LENGTH:
10”, 11”
OUTER DIAMETER:
2.2”
INNER DIAMETER:
1.5”
COLOR:
Black
  • Incredibly filling
  • Four-way adjustable straps
  • Comes in two different sizes
  • Dual-density materials
  • Only comes in one color
  • PVC is porous
  • Straps can be uncomfortable

If it’s the size you’re after, this is one of the biggest hollow strap-ons on this list. 

It’s so big, in fact, that the harness comes with shoulder straps to handle all that weight!

If you’re into bondage, this can be a huge turn-on. But depending on the position you’re in, they can also be uncomfortable and get in the way.

The dual density of the dildo means it feels like a realistic penis with a soft outer layer covering a rigid inner body. 

The internal canal features a removable tube, making it size-adjustable for those with larger penises.


11. Fetish Fantasy Unisex Hard-On Hollow Extender

PRICE:
$
MATERIAL:
PVC
LENGTH:
6”
CIRCUMFERENCE:
5.5”
INTERNAL LENGTH:
4”
COLOR:
Flesh pink, Black, Glow-In-The-Dark
WAIST SIZE:
25”- 40”
  • Affordable
  • Glow-In-The-Dark is a fun option!
  • Comfortable harness
  • Includes a mask
  • Can be too rigid for some people
  • PVC is porous

This hollow strap-on dildo offers a little texture for the receiver, bringing more stimulation into the mix.

It’s an affordable choice, making it great for beginners. Plus, the glow-in-the-dark color option is a personal favorite. 

I didn’t know I needed a glowing cock until this moment.

The PVC hollow dildo is quite rigid, though, so make sure your partner is into that before getting this bad boy. (That goes for the glow-in-the-dark feature too…)


What Is A Hollow Strap-On?

A hollow strap-on is a dildo with a hollowed-out center so it can be worn over a penis. 

Most models come with a harness, so you can strap it on securely.

The great thing about hollow strap-on dildos is that they can be worn by people of any gender – you don’t have to have a penis to wear one. 

However, they’re most often used by people who want to add extra girth, length, rigidity, or stamina to their own penis.


Why Use a Hollow Strap-On?

If you experience erectile dysfunction (ED) or premature ejaculation, a hollow strap-on dildo could be a game-changer. 

They can be worn over either an erect or flaccid penis, so if you have ED, they’re great for taking the pressure off. 

This can help you relax as well as reduce performance anxiety.

If you experience premature ejaculation because of oversensitivity, these toys can reduce stimulation to your penis. If you’d like to last longer or stay hard even after you cum, a hollow strap-on can help with just that.

To extend the length or girth of your penis, this is just the toy for the job. You can choose how much you’d like to add to your size and find a hollow strap-on to match.

Because they can be worn by anyone, they’re incredibly versatile. They’re great for pegging, trans folks, and WLW couples.


Types of Hollow Strap-ons

There are three kinds of hollow strap-ons, each with its own advantages and disadvantages. Let’s see which one might be right for you: 

TYPE
INFO
One-piece harness + hollow dildo design
These are usually the cheapest, so best if you’re on a budget. However, you can’t mix and match the harness with other dildos so you’re stuck with what you get.
Interchangeable dildos and/or standalone harness
The best harnesses have an O-ring so you can fit any compatible dildo. As usual, you get what you pay for — spending less money means a less comfortable harness.
Hollow + vibrating
Exactly like you would expect, they’re hollow strap-ons with fitted vibrators. But often the included vibrators aren’t the best quality. Look for a hollow strap-on with space to add your favorite bullet or use the toy along with a vibrating cock ring.

Choosing the Right Hollow Strap-on For You

Getting The Right Size 

This is the most important thing to think about, as the wrong size or girth will make the sex toy useless and waste your time, money, and erections. 

  • Consider the fit

    Measure yourself carefully and then check the internal length and girth of the dildo you want. Most dildos are designed to fit the actual penis of average size, but some users say that hollow dildos are better for narrower shafts. 
  • How are you going to use it

    Are you planning to use your dildo when flaccid or erect? Different dildos are more comfortable for different uses. If you want to use it mostly when erect, then a softer material and wider space would be better for you. It’s important to decide before you buy. 
  • Talk to your partner first

    You might think it’s a nice surprise, but maybe they are too tight. Maybe they don’t like certain materials. Maybe they just want your penis regardless of any issues you might have. Communication is crucial to avoid disappointments and wasted money.
  • Caution: many hollow strap-ons can be too big

    If you’re planning to use a hollow dildo when fully erect to add a few inches, be careful. Don’t let your eyes be bigger than your partner’s holes. Adding 3 inches to an already average-sized penis can be uncomfortable and even painful without enough preparation.

    If you’re not 100% certain what size they can take, be a bit conservative. Too small might be a little disappointing, but too big is just suffering. 

Material, Shape and Feel

Hollow dildos come in different angles, with defined head, without, with ridges, veins, etc.

You might have used other types of dildos in the past — think about what style were your favorites and why. 

For example, if she loves G-spot stimulation, a curved dildo would work perfectly. 

If you know you like vibrations, get a vibrating hollow strap-on. 

There’s enough variety for anyone to find what they’re looking for. 


Material Consideration

REMEMBER: If a toy goes inside someone’s body, silicone is king. It’s body-safe, non-porous and the easiest to clean. If you are not sure what material to pick? You may read our guide here.

Unfortunately, silicone toys are usually more expensive than other plastics. Materials like TPE are porous so they allow bacteria to get in. That means you have to clean them properly before and after use and dry them safely. 

Plastic hollow strap-ons are OK… if they’re from a manufacturer you know and trust. Don’t buy anything from a manufacturer you don’t know and invest in some proper sex toy cleaner. 


How To Get The Right “Feel”

Feel is a tough thing to get right. Different people want different firmnesses. My best advice is to find a product video (Lovehoney usually has one) and watch it. Does the material jiggle? Does it look hard, floppy, etc.? 

Keep in mind if you want to use it while flaccid, you’ll need more rigid material and you might need to compromise a bit on realistic skin-like softness.


Realism

There’s a whole range of realism to choose from. 

Do you want a veiny monster to match your skin tone? Or do you prefer a subtle, modern design? 

Some strap-ons have a squirting feature that simulates ejaculation by squirting synthetic ejaculate or lube. This can be a hot addition to your play session.


Detachable and Replaceable Dildo

Some strap-ons will have the harness permanently attached to the dildo, whereas others allow you to swap out the dildo. 

The latter usually uses an O-ring system and requires the dildo to have a flared base.

This second type of harness is the way to go if you want ultimate versatility. Make sure any dildo you want to use is compatible with your harness.


Ease of Cleaning

This is especially important when you’re using sex toys that can harbor dangerous bacteria.

When you’re choosing a hollow strap-on, keep this in mind. You want to make sure it’s made from easy-to-clean materials and that the inside is easily accessible. 


Harness Quality and Size

Pay attention to the harness size since even adjustable straps will have a waist-size limit.

Typically a harness will have straps that attach to your waist and over your buttocks. The most comfortable straps are the wider ones.


Vibrations

If you want extra sensations for both the giver and the receiver, a vibrating strap-on is the way to go. This is an easy way to add a little something extra to your play session without the need for another toy entirely. 

Some vibrating hollow strap-ons will have a separate remote while others use a wired remote connected directly to the strap-on itself.


Durability

The safest way to know that your strap-on will last is by checking user reviews and buying from reputable brands. A cheap sex toy might look tempting but will often compromise on materials or durability, so choose wisely.


Price

That doesn’t mean you have to break the bank when buying your new hollow strap-on. It means that you should know what you’re paying for and why. 

If budget is important to you, make sure you know what you’re giving up for the sake of a lower price tag. No matter how tempting it might be, don’t fall into the trap of compromising your safety.


How To Use a Hollow Strap-on

Those who haven’t used a penis sleeve before have this vague idea that your cock needs to be hard to put it on.

Well actually, most hollow strap-ons work best if you’re semi-hard.

And some are actually designed for men suffering from ED, so they work perfectly with no erection at all. 

The most comfortable way to put a hollow dildo on is to apply lubricant inside and then just slide it in.

Squeeze out the extra air, and you’re all set. 👌🏻

Harnesses add additional security when erection is an issue, as the straps help the dong stay in position while thrusting. 

A few extra tips on how to use hollow dildos:

  • Warm it up in warm water before as it’s not body temperature and will feel cold
  • If the dildo is larger, missionary with your partner on top will be the best position (let her control the pace)
  • Use high quality water-based lubes, because oil and silicone-based lube can damage plastics and silicone toys

How To Clean & Maintain A Hollow Strap-On

For most strap-ons, cleaning is as simple as using warm water and some mild soap or sex toy cleaner. 

You must clean the inside thoroughly. You can use your fingers to ensure you get into all the nooks and crannies.

Check the manufacturer’s instructions for cleaning, especially if your hollow strap-on has any electronic parts like a vibrating motor. 

After cleaning, let your toy dry thoroughly before storing it in a cool, dry place from direct sunlight.


Conclusion

Hollow dildos can add whole new dimensions to your sex life, but there’s a lot to consider before you just shove it in.

Do your research and don’t forget to have fun out there!
