Infinity Strapless Strap-On Pink by BMS Factory

The Infinity Strapless Strap-On Pink is a hands-free couples' sex toy that uses your pelvic muscles to stay in place, delivering dual sensation—G-spot pressure for you and penetration for your partner—without a harness.

What it does

The strapless design works by anchoring a curved internal bulb inside your vagina while the external shaft extends outward to penetrate your partner. As you thrust, the internal bulb rocks against your G-spot, building sensation with each movement. Premium silicone flexes naturally with your body, staying positioned exactly where you need it during vigorous sessions without the bulk or hassle of a harness.

Your arousal heightens as your pelvic muscles grip the internal portion tighter, creating powerful contractions that pulse through both ends. Every thrust your partner receives sends feedback through the internal bulb directly to you, creating deeper intimacy because you feel exactly what they feel. Many reach intense orgasms from this dual sensation of giving and receiving simultaneously. Browse Pornhub Sextoys for other couples' options if you want to explore further.

Fit and sizing

Size depends on your comfort and your partner's preference, not your anatomy. The 8-inch total length with a 4-inch external shaft suits most couples, but only you and your partner know what feels right during sex. Start by inserting the curved bulb until it sits comfortably against your G-spot, then adjust your body position so the external shaft angles naturally toward your partner. Strong pelvic floor muscles make this sex toy much more effective, so kegel exercises before you start help immensely. Cockringshop specialise in products for men and couples, and our team can answer sizing questions by email or phone if you're unsure.

How to use it

Apply generous water-based lubricant to both the internal bulb and external shaft before insertion. Slide the curved bulb inside your vagina until it sits comfortably against your G-spot. Your pelvic muscles will naturally grip around the narrower neck to keep everything in place. Position yourself so the external shaft extends outward at a natural angle for penetrating your partner.

Start with slow, controlled movements to find your rhythm before building pace. Squeeze your internal muscles periodically to maintain grip and create additional sensation—the tighter you contract, the more pressure you'll feel against your G-spot. Watch for your body's signals: increased wetness and sensitivity show you're hitting the right spots. Rinse thoroughly with warm water after use and allow to air dry.

Feature breakdown

Who it suits

This strap-on works best for people with strong pelvic floor muscles—regular kegel exercises make a real difference. Partners who enjoy giving as much as receiving find this incredibly fulfilling because every movement you make directly affects their pleasure too. Those seeking deeper emotional connection during sex appreciate the skin-to-skin contact this enables. Couples who want dual sensation from a single sex toy, where both partners climax together, love the shared feedback.

Skip this if you prefer hands-free options where you don't need to actively thrust or grip with your muscles. It's not ideal if you have difficulty with vaginal muscle control or find kegel exercises challenging. If you want something that requires no physical effort from your body, a vibrating couples' sex toy or a traditional harness strap-on might suit you better instead.

How it compares

Strapless strap-ons differ from harness-based designs because they rely on your pelvic muscles to stay in place rather than external straps. This means more skin-to-skin contact and direct feedback, but they require stronger muscle control and active participation during thrusting. Harness strap-ons offer hands-free penetration once positioned, but they create a barrier between your bodies. Silicone flexes naturally, while rigid materials stay fixed. Explore Adam Eve Sextoys for alternative strap-on styles if you want to compare harness-based options.

What you can use it with

Pair this with cock rings to help your partner maintain his erection during longer sessions, or combine it with prostate toys for added sensation on his end. Couples Intimacy Kits bundle complementary items that work together during partnered sex. Adding a second vibrating toy for clitoral stimulation while you use the strap-on intensifies sensation for both of you. Experiment with positioning aids or furniture designed for couples' play to find angles that work best with the 4-inch external shaft.
