A cock ring is a adult toy designed to be worn around the base of the penis or both the penis and testicles. It helps maintain erections by restricting blood flow, enhancing stamina, and intensifying pleasure. Cock rings come in various materials like silicone, rubber, or metal. To use, place it around the base when semi-erect, ensuring comfort and safety. Avoid prolonged use (typically under 30 minutes) to prevent discomfort or circulation issues. Always prioritize safety and lubrication.
