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.
Penis rings come in many different shapes, sizes and materials.
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.
With all of that bloodflow, most men experience an increase in sensitivity throughout the penis. Wearing a cock-ring can increase the sensitivity quite a lot.
Assisting the penis in retaining its increased blood volume will definitely help with stamina and prevent premature ejaculation and for some men, it can even assist with erectile dysfunction.
For use, it is suggested to put the cock ring on while semi-erect. As a cock ring works by temporarily reducing blood flow to the penis, you must not wear a cock-ring any longer than 30 minutes.
