Cock rings and sleeves are two sex toys designed to enhance male pleasure and performance during sex. A cock ring is a small, ring-shaped toy placed at the base of the penis to restrict blood flow and help maintain a firmer, longer-lasting erection. On the other hand, a sleeve is a textured sheath that can be placed over the penis to provide additional stimulation during sex. These toys can be made from various materials, including silicone, TPE, and latex. They can be used for solo play or with a partner to enhance sexual experiences.
