Enjoy an intense sexual experience with this 3-piece cock ring set! The rings are made of soft and flexible silicone for a good and comfortable fit. Place the ring around the base of the penis when the penis is flaccid. During an erection, the ring limits blood flow for a harder and long-lasting erection. This also makes orgasms feel more intense.
