Use of a cock ring gives a man a stronger erection & a more lasting sexual experience. Many rings are not adjustable & can be more uncomfortable than they are productive. This red erection ring is fully adjustable so it will accommodate a man of any girth. It can be used alone or with a condom. It is worn at the base of the shaft where its pressure will keep the blood flow constant in the penis thus helping to maintain an erection. Some men also enjoy a larger penis during intercourse when using a cock ring.
