This super-soft silicone feels great next to the skin, while the unique non-slip design keeps the ring in place throughout your playtime. The level of stretch is less about the size of your penis, but more about the level of intensity you're looking for. The maximum level of stretch is great for new users, those with more girth, and those looking to use the ring around both the penis and testicles. Use around the base of the penis to restrict blood flow, giving you a fuller and harder erection. Use around the testicles to keep them from contracting, prolonging your orgasm from 5 seconds to up to 50 seconds. You can even use it around both the penis and scrotum for an even more intense experience (after some practice!) . Body-safe (100% silicone with absolutely no phthalates) . Non-slip design . Super easy to put on . Extra comfortable to wear . 100% Waterproof . Boil-able & dishwasher Safe
