A cock ring is a ring of material that a man wears around the base of his penis and scrotal sac; it stops blood from moving away from the penis to make orgasm more intense.
Men use cock rings for many different reasons:
- To create the sensation that something is holding onto the penis and balls
- To help maintain a stronger, firmer erection
- To keep an erection for a longer period of time
- To make the penis more sensitive to all kinds of stimulation
- To prolong intercourse
- To delay ejaculation

Vibrating Cock Rings: Something for Him and Her
Vibrating cock rings come in several different designs and work especially well during vaginal intercourse. When using make sure the vibrator sits on top facing you, so that as you penetrate her vagina, the vibrator sits on top of the base of your penis as well as her clitoris.
