A device used to ensure that the wearer does not have sex, or, in some cases, have any form of sexual stimulation such as masturbation.

In modern times, mostly used as a component of BDSM. The wearer will be put in the belt and surrender the key to another person, who then has (theoretically, effectiveness varies depending on the person and the device) complete control over the wearer's sexual release.
I always make my slave wear a chastity belt; by the end of a week in it, he's so desperate for release he'll do anything!

The same as a cock block, just for women. This usually occurs among twins or a group of awkward females. A male that can hit on both parties during a chastity belting gains manliness instantly.

A device worn around the genitals in order to protect against rape, discourage sex, or control masturbation.
I have made my son wear a chastity belt at all times since he was 10. He is 17 now and I have the key hidden to give to his wife when he marries. He is very well behaved and has never been able to masturbate. The belt is designed to allow urination without removal, so it can be left on all the time! I will continue this practice with any future sons.

A belt worn to keep you from getting raped, made from lead and metal, looks kind of like a baby swing at parks. Used in the olden days and still used in some jails.
