Nexus Ultra Si Dual Perineum & Prostate Massager

Nexus Ultra Si is a dual prostate and perineum massager with a smooth, ergonomic shape for targeted internal pressure, plus a small metal ball at the base that rolls against the perineum for that “licked” feeling. It’s waterproof and designed for hands-free stimulation through body movement during sex or solo play. 

Ultra Si is made for direct, controlled prostate contact. The curved shaft helps you find the sweet spot without awkward angles, and the external base gives you a stable grip for easy positioning and removal.

The standout detail is the perineum roller. As you shift, thrust, or gently rock the toy, the metal ball moves against the perineum and adds a second layer of sensation—inside and out at the same time.

How to use: Apply plenty of water-based lubricant. Insert slowly and angle the curve towards the prostate. Let the base sit against the perineum so the roller ball can move with you. Use gentle rocking or natural body movement to change pressure and sensation.

Cleaning & care: Wash with warm water and mild soap (or toy cleaner), rinse well, and dry fully before storing.
