A cock ring or cockring is a ring that is placed around a man's penis, usually at the base, primarily to slow the flow of blood from the erect penile tissue, thus maintaining erection for a longer period of time. Cock rings can be worn around just the penis or penis and scrotum, or just the scrotum alone, though this is usually designated as 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. The term cock ring is sometimes used as a synonym for a Prince Albert piercing, a piercing of the penis that is usually, though not always, a metal ring.
A man may wear a cock ring because he has erectile dysfunction (ED), erectile hyperfunction, or otherwise wants to prolong erection because he 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. When used for ED, a vacuum pump is used to produce an erection in spite of vascular or nerve damage, and the ring slid off the pump's cylinder onto the base of the penis to maintain the erection.
Some men enjoy using cock rings for masturbation, as wearing of this sex toy contributes to better erection and delays orgasm, thus it intensifies orgasmic sensations. Also vibrating cock rings deliver a great range of very pleasurable vibrations that enhance enjoyment.

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. For rings made of elastic material, it may simply be stretched over the penis and scrotum and situated against the body. However, with rigid rings made of plastic or metal the process is different. 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. 
Some models include a protruding clitoral stimulator, designed to tickle the clitoris, vulva, or anus during sex. Others, such as the Vibrating ring, vibrate, either vibrating the ring itself, or in a popular 'Dolphin' variant using two removable bullet vibrators to provide stimulation to the testicles and clitoris. Some cock rings have vibrators attached that can be worn to stimulate the scrotum or perineum of a partner during sexual intercourse. Many women find that rings with vibrator attachments provide clitoral stimulation that is needed for achieving orgasm. Cock ring users should keep in mind that any pain, discomfort, or feeling of coldness in genitals is a signal to take the cock ring off.
Another variation is an inflatable cock ring for added control of adjustment.
A triple cock ring or triple crown is a cock ring that has additional rings for restraining the testicles. In orgasm, the testicles usually retract towards the body before ejaculation. A triple crown changes and intensifies the sensation of orgasm by forcing the testicles to stay away from the body.
Vendors of cock rings always indicate that cock rings are not to be worn for more than 20-30 minutes. Falling asleep or using illicit drugs at the same time is very dangerous. The first sign of pending problems are when the penis starts to become numb or white. As soon as this happens, the cock ring must be removed. 
To ensure that cock rings easily come off, the latest cock rings have quick release mechanisms so one does not have to struggle with pulling the rubber ring from the base of the penis. Cock rings should not be used by individuals who are on blood thinning medications, diabetics, those who have heart disease or sickle-cell disease. Other problems with cock rings are that many do slip off or get caught in pubic hair. Some can cause severe tightening of the scrotum. Cock rings are best used with some type of personal lubricant.
 Medical issues
Cock rings that are too tight, or worn for too long can be dangerous: this may cause priapism, a medical emergency that, if not treated promptly, can result in severe and permanent damage, including penile gangrene that can result in the destruction and possible amputation of the penis. Rings for erectile dysfunction are invariably supplied with the instruction that they should not be left on for more than thirty minutes. Falling asleep with a ring on is a particular danger. This may lead to temporary or permanent nerve damage. Numbness in the glans penis, penis becoming cold or penis becoming white may be signs that a cock ring has been worn for too long and medical advice should be sought.
Elastic, stretchy, cock rings are removed by stretching them and pulling them off the penis, over the head, which can be difficult. Others have a quick-release mechanism allowing them to be easily removed without the need to do this. Some (not for erectile dysfunction) are designed to allow limited blood return, such as by hard beads that cause the ring to roll back and forth during use, increasing circulation.
When used for extreme or total erectile dysfunction, it must be possible to fit the ring onto the erect penis immediately after an erection has been produced by the pump; this practically mandates the use of very flexible rings that can be fitted on the outside of the pump's cylinder, and slid onto the penis without removing it from the cylinder when erection has been maintained.
Cock rings must not be used by those who have cardiovascular problems, diabetics or those who take any blood-thinning medications.
 Materials and types
Cock rings are made from many materials including leather, rubber, silicone, nylon, metal and even plastic. Many of the newer rings also have different accessories and projections. There are also vibrating cock rings available which can stimulate the testes at the same time. 
Today, cock rings can be bought with accessories that stimulate the clitoris or anal area during intercourse. Other cocks rings go around the scrotum and can significantly enhance erection and intensity of orgasms.
However, there is one negative; the more accessories that are added on, the greater the chance of developing discomfort or cold sensations from the device. There is specialized underwear which come with pre-fitted cock rings. The underwear has a pouch with a C ring which either slides along the penis or encircles the scrotum. As one walks, the C ring enhances the erogenous zone.
 Specialized underwear
Underwear, similar to this front stitched men's thong, can have built-in cock rings, companies such as California Muscle
specialize in the products.
Some underwear for men features a pouch with an internal fabric/elastic cock ring, or "c-ring", that either slides along the penis and encircles the base of the testicles or, alternately, simply snaps around the base of the testicles to snugly--but not in a constricting way--attach the pouch to the genitals. While this type of pouch permits the wearer to "go backless," c-ring pouches can be attached to either a thong or traditional jockstrap.
