Cock rings are rings that fit around the penis and/or scrotum. They decrease blood flow to the erect penis and can help the erection last longer. Some also have buttons or small vibrators to increase pleasure for you and your partner. Cock rings are also known as penis rings, tension rings, and constriction rings. They are sometimes marketed as rings for erectile dysfunction (ED), but even people without ED use them.

Increased stamina: There is anecdotal evidence to suggest that a cock ring can help increase sexual stamina. However, a previous study (Trusted Source) conducted on men with premature ejaculation found that using a cock ring did not improve this sexual dysfunction.

Erectile dysfunction: For men who can achieve an erection but have difficulty maintaining it, a cock ring may be helpful. A cock ring retains blood within the penis, which can help keep it harder for longer. If a man can't achieve an erection, he can combine a cock ring with a penis vacuum pump, also known as a penis pump.
