Experience the incredible sensation , 10-function, medical-grade silicone, vibrating cock ring. Because of its unique patented infinity design, when worn at the base of the penis, it will not slide up or down the shaft, thus helping achieve a harder, bigger and longer erection. Cock rings work by constricting blood flow and keeping blood in the shaft of the penis. When the user finally does ejaculate, the sensation is more intense, since it took longer to come, and because the penis is filled with additional blood, the orgasms are also more intense.
