Chastity: In BDSM, chastity is the practice in which a man, normally through the help of male chastity devices, willingly or unwillingly prevents himself from physically stimulating his penis (either through intercourse or masturbation)

The locked: The individual giving up his right to control and use his penis for sexual enjoyment and release. Is not necessarily submissive by nature and could be dominant in other aspects of life outside of sex.

The key holder: The individual who physically possesses the "keys" to the chastity cage. The key holder possesses the power to unlock the chastised male’s cage and allow him the ability to experience an orgasm. As key holder, you are expected to create rules. Rules are a simple way to enforce the chastity, reinforce trust, and to devise a suitable punishment for when there are infractions to the rules.

The rules: Rules might be simple; in the sense that the locked can earn freedom by doing household chores, or that he is allowed to take the cage off after x amount of days. They can also be more complex. For example, you have the locked make you orgasm x amount of times before he is released, and if the sexual activity wasn’t good enough or there wasn’t enough effort then x amount of days are added to his cage time.
