When you slip the snug-fitting around the base of your shaft, it works like a tourniquet to cut off the regular flow of blood. This causes blood to pool in your shaft to give you a thicker and possibly even longer shaft. Like a tourniquet, you can't use penis rings for extended periods of time so make sure you take it off after 20 minutes. The outside of each penis ring is covered with small ribs to rub against her clit and vagina during sex for extra stimulation. The three penis rings measure 1.5, 1.75 and 2 inches in diameter - giving you a wide assortment to try. All the rings are made from silicone. Not only is silicone considered a hygienically superior material, but it's also extremely durable and stretchy. It even naturally retains its shape, which makes it the perfect material for rings. Adam & Eve recommends the Ultra Sweller Cage for couples to use during sex. The penis rings are compatible with Adam & Eve's water-based sex lubes. Wash the rings in warm, soapy water after use and rinse them clean. Let the rings dry before storing them with the rest of your sex toys.
