An anal hook is a sex toy often used in BDSM to create a sense of control, bondage, and pleasure. It usually consists of a curved metal hook with a ball or padding at one end and a loop or handle at the other. In BDSM, the use of an anal hook can be part of an erotic experience where one partner can lead or control the other by attaching the hook to the submissive's anus. It can also be used as a form of punishment or reward within a dominance and submission situation. When using an anal hook, it is important to use enough lubricant to minimize discomfort and the risk of injury.
