A steel cock ring is a rigid, non-flexible ring made from stainless steel or other metal, designed to be worn around the base of the penis or both the penis and testicles. Unlike stretchy rings, steel cock rings provide a firm, unyielding grip, which restricts blood flow to help maintain a harder and longer-lasting erection. The solid construction delivers more intense constriction, making it ideal for those looking for a tighter, more advanced experience. Steel rings also offer weight, which can add a different sensation during wear.
