A device designed to go around the base of an erect penis that prevents blood from returning from the penis and therefore helps an erection to last longer. Such a device can either be produced for this purpose and sold along other sex toys, or an object such as a hair scrunchie without metal can be use as a substitute. One must take care to not get the penis ring too tight around the penis, it should be light pressure and not painful.
