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.

Best Hollow Strap-on Dildos for Men

CalExotics Silicone Hollow Strap-On Dildo

1. CalExotics Silicone Hollow Strap-On Dildo

Best budget pick

Price: $ | Material: Silicone | Insertable Length: 6.5” | Circumference: 6” | Color: Vanilla, Chocolate | Waist Size: Stretchy

  • 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. 


Doc Johnson Be Naughty

2. Doc Johnson Be Naughty 

Upgrade pick – most versatile

Price: $$$ | 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.


Fetish Fantasy Extreme

3. Fetish Fantasy Extreme 

Best for size – biggest size and girth

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 core inside, 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! 


 Lovehoney Perfect Partner

4. Lovehoney Perfect Partner

Best vibrating hollow strap-on

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. 


CalExotics Packer

5. CalExotics Packer

Best hollow packer 

Price: $ | Material: Silicone | Length: 4.5” | Circumference: 1.5” | Color: Vanilla, Cashew, Caramel, Chocolate | Waist Size: N/A

  • 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. 


RX Sleeve

6. RX Sleeve

Best premium extender for ED

Price: $$$ | Material: Platinum Silicone | Length: Variable | Insertable Length: Variable | Circumference: Variable | Color: Vanilla, Coco, Caramel | Waist Size: Up to 60”

  • Hyper-realistic
  • Top-quality materials and design
  • Customizable
  • Expensive

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. 


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: 

TYPEINFO
One-piece harness + hollow dildo designThese 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 harnessThe 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 + vibratingExactly 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 average penis, 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 harness. 

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. 

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.


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 it 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

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!
