    Hollow strap-ons are perfect for anyone struggling with erectile dysfunction, premature ejaculation or that would like to please their partner with a bigger size. 

    Product description

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

    Both the hollow 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.

    Do you love something specific about it? Do you recommend a certain way to use it? (in the shower, alone, with a partner, daily etc.?)

    Recommend for...
    Spiciness: 2 chili spiciness
    Experience: recommended for Beginners

    Although this is marketed a unisex toy, it functions best worn over a penis, as this adds stability to the shaft. 

    This is a great option for anyone with erectile dysfunction, premature ejaculation or wants a bit of extra size. 

    Product description

    A realistic-looking strap-on that can go for an unreal amount of time! This hollow strap-on from Fetish Fantasy is sure to fulfill 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.

    Conclusion

    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. This also means it can have a plastic smell, especially when it’s new.

    This is great for anyone who has erectile dysfunction or premature ejaculation and enjoys vibrations.

    Product description

    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.

    User reviews

    Conclusion

    The best thing about this toy 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.

    Conclusion

    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.

    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.

    Designed to be worn over a penis or vagina, this toy is perfect for recipients who crave the feeling of fullness. 

    Product description

    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.

    Conclusion

    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.

    Conclusion

    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.

    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!

    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.

    Fetish fantasy hollow strap on

    Internal canal size

    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

    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.

    How to clean a hollow strap-on

    Keeping your hollow strap-on sparkling clean is paramount! You need to make sure that it is cleaned thoroughly before and after each use. Always follow the manufacturer’s instructions for cleaning your sex toys.

    FAQ

    Hollow strap-ons are a great, non-invasive option if you have erectile dysfunction as they allow you to have sex with your partner even if you are unable to get or maintain an erection. As your penis sits inside the dildo, you can thrust naturally and enjoy the stimulation from the dildo over your penis, while you also please your partner.

    This depends a lot on the material of the hollow strap-on, particularly the material of the inner canal. Some tend to be harder and others softer. The other thing is that although you will still feel sensations from the dildo over your penis, you won't get the same sensory feedback you would usually get from being inside your partner, which can make it difficult at first and can take some time to get used to.

    The short answer is, don't! We love a good sex toy DIY but safety always comes first. As a hollow strap-on will be sitting over your penis and entering your partner, it's not worth taking any risks with getting it wrong. Stick to buying body-safe toys from reputable shops.

    Yes! Hollow strap-ons are safe to use as long as you follow some simple rules. 

    1. Make sure the canal size isn't too small. You should not feel any pain when using a hollow strap-on. If you feel pain or the blood flow to your penis becomes restricted, remove the strap-on and look for a toy with a bigger canal size.
    2. Make sure the dildo isn't too big for your partner. Again, this shouldn't be uncomfortable or cause any pain.
    3. Take things slowly, both you and your partner need to get used to the added size. You also don't get the same tactile feedback as you would usually so communicating with your partner is key.
    4. LUBE! Always use plenty of lubrication in the inner canal and outside of the dildo to make for a smooth ride!
