Strap-on Sex
In BDSM practice, also known as Strap-on Fuck, Strap-on penetration, or simply Straponization, this is vaginal, anal or oral penetration with a strap-on dildo. It is most often performed by the female Dominant (see Domme) to male submissive as an act of superiority. When a woman penetrates a man's anus with a strap-on dildo, the practice is known as Pegging (see FemDom).
