What is a cock ring?
A cock ring is an object that typically goes around the base of both the penis and scrotum. Since veins are closer to the surface of the skin than arteries, this has the effect of allowing blood to flow into the penis but restricts its ability to flow outwards. In turn, this makes the penis get hard and stay hard for longer. Obviously, for this to work a cock ring must be put on when the penis is unerect. Most cock rings are made of chromed steel or rubber. In fact, most of them are little more than high-priced gasket rings or chrome- plated circular chain links one could buy at any hardware store. They have to be chosen carefully, sized for the user. A too-loose cock ring does nothing, a too-tight cock ring cuts off all retreating blood flow, thus preventing the cock from ever getting soft, which may sound like fun but can become painful after two or more hours, and which may require a trip to the emergency room to remove. Some cock rings that get around this problem are made with snaps at different places along a strap of leather, therefore making it easy to size and to remove.
