What Is A Thrust Buffer: The Definitive Guide


This patented, first-ever adult product cushions deep thrusts during intercourse, providing an opportunity for more passionate sex without restraint. Acting like a cushion between two partners, it absorbs the impact of bumping together, while providing the sensation of maximum depth for the penis.

Receiving partners who express discomfort during intercourse with a partner may find pleasure in a thrust buffer’s ability to make sex more enjoyable within their comfort zone. Penetrating partners will still have the feeling of full insertion and intimate contact with their partner without having to hold back. For women, buffers also act as a sexual health tool to lessen the chances of a bruised cervix.



The Bumper® is a system of two parts: The Bumper® Thrust Buffer™ and the Donut Buffer. Either one can be used independently or together to create a thick, protective cushion for deep thrusts. 

The Bumper® fits around the penis and is held in place by the testicles. It is also designed to be adjustable. Users can easily add more cushion with Donut Buffers to suit their depth and comfort requirements.

Thanks to The Bumper® , sexual partners can now try previously avoided positions with renewed confidence and pleasure.



While The Bumper® is a truly outstanding product, and one that can stand on its own, adding extra Donut Buffers can greatly increase comfort and pleasure, for both partners!

To use, simply slide The Bumper around the penis, allowing the testicles to slide gently into place. Check out the informational video on our website for a visual representation. 

Once in place, simply slide one or multiple buffers onto the penis for additional cushion.

Adding buffers will still allow the penis to experience maximum depth, it simply reduces penetration depth for the receiver. Reducing penetration depth can increase comfort and reduce the chances of pelvic or cervix bruising, no matter how feisty your play. 



The Bumper®. Created by Perfect Fit Brand™ it’s the first patented bumper of its kind. It reduces penis penetration depth and provides a softer cushion for “bumping” into your partner. Simply put, it provides more “cushion for the pushin’” – literally!

“...it’s a relief to find a product that stops a penis from penetrating too deeply AND maintains a more natural feel for both partners. I have a weird habit of wanting to get right down to the hard boning and that, combined with my partners’ endowment (as it were) has led me to sex-injure myself on numerous occasions. The Perfect Fit Brand® Bumper Base & Donut stopped me from hurting myself…” ~This quote was originally published on RedHeadBedHead.com

The Bumper® is a two-part system comprised of The Bumper® Thrust Buffer™ and the Donut Buffer. Either part can be used independently. Alternatively, they can be used together to create an even thicker cushion. 

Use it to reduce the penetrative length of a penis or strap-on dildo, while still providing that full penetration sensation. Women appreciate that it lessens the chances of bruising the cervix – without having to feel the need to hold back during those heated moments. Made from Perfect Fit Brand®’s proprietary SilaSkin™ material, both parts are irresistibly soft and comfortable to use. 

Donut Buffer. Designed to work with The Bumper®, the Donut Buffer further reduces penetration depth of the penis or strap-on dildo. Multiple Donut Buffers can easily be stacked to create even greater reduction in depth. It can also be useful to prevent unwanted contact with dildo-harness attachments.

Made from the same proprietary SilaSkin™ material, The Donut Buffer is super soft and stretchy. Get creative!



Have you ever thrust passionately into your partner, only to hear them wince in pain? Is your penis a bit “too much” for your partner? If so, The Bumper® may be for you! It quickly and easily reduces the insertable length of your penis. But, don’t worry… with The Bumper®, you’ll still retain that full insertion feeling!

For women who have experienced bruising of the cervix due to a penis that is simply mechanically incompatible with her parts, The Bumper® is the perfect solution. 



There are lots of simple things you can do to reduce pain and discomfort during sex. First and foremost, always keep an open line of communication between you and your partner. Trying something new? Communicate expectations prior to and during sex. Maybe even do a little debrief afterwards. 

Changing positions is a great way to adjust penetration depth. Explore different positions to find one that works well for you and your partner. Lubrication also helps. Stimulate natural lubrication with extended foreplay sessions or use a bottled version. 

Buffers are an incredibly useful tool to make sex as comfortable as possible without having to restrain passionate thrusts. Not only do they reduce the insertable length of the penis (without affecting the wearer’s sensation), but they can also act as a cushion between pelvic regions. There’s no need to suffer through painful sex. Communicate with your partner and find a solution that works for both of you.
