A cock ring is an easy-to-use, effective way to enhance orgasms. It works by restricting blood flow to the dick, which fills it with hot, throbbing, erogenous tissue and increases orgasms and sensations. Cock rings are available in a wide variety of sizes and materials, from soft stretchy material to firm metal. There's also a choice of features, such as built-in vibrators or a quick-release snap. The best one for you depends on your needs and anatomy, but it's important to listen to your body. If your cock ring feels painful, that's a sign it is too tight and should be removed immediately.
To find the right cock ring for you, it's best to start with something soft and easy on (but not too loose) to get the hang of using one. A good choice for beginners is a rubber or plastic ring that is inexpensive, safe and can be cut to size with scissors. Some people prefer a softer ring that's more forgiving to kinks, while others like hardier material or a ring with snaps that can be easily released when needed.
Once you've chosen a ring, put it on while the penis is flaccid or semi-erect and slide it to the head and down the shaft, applying lube as needed. The ring should be tight enough to feel secure, but not so tight that it's painful or difficult to use. Some beginners may find it easier to slip the ring on while the penis is already erect, but if this feels uncomfortable or painful that's a sign it's too tight and should be removed. For safety, don't wear a cock ring for more than 20 or 30 minutes at a time. Cutting off fresh blood flow for too long can damage the ring or cause pain or numbness.
