A chastity belt is a physical device designed to restrict a person's access to their genitals, often for extended periods. In the context of BDSM, the chastity belt serves as a tool for the dominant to exert control over the slave's body and desires. The belt can be made of various materials, such as metal, leather, or plastic, and may feature additional restraints, like locks or padlocks.
Often, chastity belts are associated with the Middle Ages. However, most historians agree that the stories and illustrations from this period suggesting widespread use of chastity belts were likely exaggerated or fabricated. The few verifiable instances of their use suggest they were not common.
