Penis cages are derived from the now centuries-old chastity belts. The first stories about these belts date from the early 15th century. A chastity belt was worn exclusively by women at that time . It was inappropriate to have intercourse before marriage, and masturbation was also out of the question. So when the men were away from home for a while, the woman was fitted with a chastity belt to make sure she could not commit adultery. The chastity belt was a lock-secured garment that was worn around the hips like underwear. Chastity belts are still available today, only the function and target audience has changed over time. For example, the belts are now also marketed for men . Chastity belts and penis cages are nowadays increasingly worn within the BDSM world . A chastity device can be an exciting tool to use in a game of power and impotence.
