Cock Rings
A cock ring is a type of sex toy typically made from rubber, silicone, or metal, designed to be worn at the base of the penis, sometimes also including the testicles. Its primary function is to restrict blood flow out of the penis, thereby enhancing the hardness and endurance of an erection. Some cock rings include additional features, such as vibrating elements, that can provide extra stimulation during sexual activity. There are also cock rings designed to be used in conjunction with a partner's sex toys, for example, to enhance stimulation of the partner's vagina or clitoris.
