Stretchy Cock Rings
A flexible and stretchy cock ring is usually made of silicone or a rubber-like material. Its stretchy properties allow them to stay comfortably in place without losing the pressure required to provide an improved and long-lasting erection.
Stretchy penis rings also give you the opportunity to find a penis ring in the right size. Thanks to its flexible material, most of these rings fit most sizes - it's only the size that determines how tight it fits around the penis.
With the help of water-based lubricant, a penis ring becomes easier to put on.
