Female chastity belts are a form of sexual bondage in which a woman is restrained to prevent her from engaging in sexual activity. The chastity belt is most often used by males to control the female partner's sexual activity and can be considered an extreme form of BDSM.  Female chastity belts are designed to prevent the wearer from being able to touch her genitals, with the intent that this will make her more sexually submissive to her partner.
