Cock ring

A cock ring is a ring that can be placed around a penis, usually at the base, primarily to slow the flow of blood from the erect penile tissue, thus maintaining an erection for a much longer period of time.

Cock rings can be worn around just the penis or both the penis and scrotum, or just the scrotum alone, though this is usually called a testicle cuff. Rings can be made of a variety of different materials, most commonly leather, rubber, or silicone, though nylon and metal are also used either as the main component or part of the closure.

When used in cases of erectile dysfunction they are known by various names such as "erection ring" and "tension ring".

A man may wear an erection ring because he has erectile dysfunction (ED). When used for ED, a purpose-designed vacuum pump is used to produce an erection by simple mechanical and hydrodynamical action in spite of vascular or nerve damage, and the ring is slid off the pump's cylinder onto the base of the penis to maintain the erection before it is lost. The testicles are not ringed in this case.

A cock ring may be used to prolong erection in order to provide pleasure beyond their own orgasm or simply because the wearer likes the particular sensation of tightness and extreme engorgement that wearing one provides. It can be worn as a sex toy, as genital jewelry, or simply for the appearance. Some men enjoy using cock rings for masturbation, as wearing of this sex toy contributes to better erection and delays orgasm for themselves, thus it intensifies orgasmic sensations. Also, vibrating cock rings deliver a great range of very pleasurable vibrations that enhance enjoyment for the wearer and their partner.

The purpose of a cock ring is to trap blood inside the penis in order to maintain an erection, or encourage a stronger erection. In order to do this it must be placed at the base of the penis.

A ring made of stretchy material is simply stretched over the penis (and optionally also the scrotum, except when used with a pump for impotence) and situated against the body. Rigid rings are used differently: first each testicle is fed through the ring and the entire scrotum is pulled through, then the flaccid penis is pushed through the ring and situated against the body. When used with a pump, a lubricating gel is always used to help the pump maintain a vacuum, in the same way vacuum grease is used with a vacuum pump in scientific applications. The gel also makes it easier for the ring to slide off the pump, and later, to remove it from the penis.
