BDSM gear that’s used by those unfamiliar with it includes nipple clamps, butt plugs, and dildos; but as you explore deeper into this rabbit hole of sexual fantasy you might also come across videos using anal hooks as sexual toys.
Anal hooks are typically constructed of steel or other metal and feature a circular hoop at one end that fits directly into your anus. Some models feature interchangeable heads to allow users to insert different-sized balls or tear-shaped butt plugs, while others may only come equipped with one ball or twist end.
Your choice of anal hook will depend on its intended use; for solo sessions or use with partners/groups. Smaller hooks tend to be easier to manipulate while larger models provide greater leverage when playing together.
