Slide the supple, stretchy ring down and around the base of the penis (include the testicles, too, if the ring fits!) -- and keep the diamond on top to treat your partner to blissful clitoral stimulation. Flip it upside down for intense external perineum stimulation, or double-loop it on your hand and wear it as a flashy finger vibe! The high-powered single speed motor does double duty, serving up pleasure for two with the simple push of a button. Erection rings work by restricting blood flow at the base of the penis. As a result, enjoy longer erections as well as a fuller feel! Use a cock ring as a stamina training tool if you're looking to extend the duration of your sexual repertoire.
