Anal fisting is a kind of sex involving insertion of the hand into the anus. Though possible, rarely is the hand initially inserted while balled in a fist. The hand enters the anus slowly while the fingers are straight and together, then balled into a fist once fully inserted. "Punching" is the term used when the hand is forcefully inserted while initially in a fist.
It is a form of sexual behavior considered to be comparatively high in risk, due to the vulnerability of the tissues and the septic nature of the anus. As the rectal mucosa provides little natural lubrication, a personal lubricant is most often required or preferred when penetrating the anus. Related Episodes & Trailers:
