Editing Cock ring (section)

==Uses==
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 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 the ring is situated against the body.<ref>[http://www.freddyandeddy.com/howto/howusecockring.htm Freddy and Eddy: How Use a Cock Ring<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20180129024220/http://www.freddyandeddy.com/howto/howusecockring.htm |date=2018-01-29 }}</ref>

=== Medical ===
An erection ring may be worn to treat [[erectile dysfunction]] (ED). When used for ED, a purpose-designed [[penis pump|vacuum pump]] is used to produce an erection by simple mechanical and hydrodynamical action in spite of [[blood vessels|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. When used with a pump, a [[personal lubricant|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.

===Recreational===
A cock ring may be used during sex or masturbation to prolong or enhance erections, delay orgasm, or for the sensation of tightness and engorgement that wearing one produces; vibrating models apply vibration to the base of the user's penis and to their partner. They can be worn as [[sex toy]]s or for aesthetic reasons.
