This cock ring is amazing - it's made of silicone, and slips on and off without catching his pubic hair (unlike some cheaper cock rings do). My fiance and I love the vibrating bullet to be either in the bottom to stimulate his testicles, or on top to stimulate my clit. This toy is our go-to travel companion, as it's not bulky, and the bullet can be removed and double as a clit toy.
