Verge fits around the penis and testicles of the penetrating partner to stimulate their perineum during sex. (It’s best to put it on before their erection starts. Put one testicle through the loop at a time, then the penis.) You can control Verge manually—just press the power buttons on its side to cycle through ten vibration modes—or connect by Bluetooth in the We-Vibe app.
