Crotch
From wipipedia.org
The crotch is the area of the human body at the bottom of the torso, between the tops of the legs. Since it is the location of the principal sex organs and the anus, it is the focus of much sexual and BDSM activity.
The crotch is also that part of an item of clothing, e.g. on leggings, that covers the body's crotch.
