Cock Rings
A cock ring or c-ring is often worn around the scrotum and base of the penis.
The primary purpose of wearing a cock ring is to restrict the flow of blood from the erect penis. This often produces stronger erections that tend to last for a longer period of time. Sometimes cock rings are worn just as decoration, basically jewelry for your dick. There are also those who wear cock rings to accentuate their junk.
Some different types of material Cock Rings are made of include; metal, rubber, leather, and neoprene, just to name a few. Certain rings come with vibrators or various types of anal and clitoral stimulators. Rings are available in a variety of shapes and sizes. Extreme care must be taken while wearing a cock ring to ensure you don't do any permanent damage to yourself.
