Anal fisting is a sexual practice in which one partner inserts a hand into the other's rectum through the anus. The practice is similar to vaginal fisting.
The person who is inserting their hand is called the fister and the person receiving is called the fistee. Despite the term's name, the hand is not actually in a fist position during insertion. To slide the hand inside the anal cavity past the anus, the fingers are extended and overlapping in a cone shape, sometimes referred to duck-billing or the "silent duck."
The sensations the receiving partner feels during anal fisting are different for everyone. However, many people like the pleasurable fullness. For people with prostates, fisting can also provide an intense prostate massage. There is even a recognized National Fisting Day in October to celebrate the act.
Best Positions for Anal Fisting
The most successful positions to achieve full-hand insertion are with the fistee laying on their back, in the doggy style position on their hands and knees or in a sex swing.
Gradual insertion stretches the anus to accommodate the fingers, knuckles, hand and thumb, until eventually retracting again around the wrist. Once the hand has fully entered the rectum, the fingers can be moved or clenched into a fist. Anal fisting is mainly a partnered activity, though some people can achieve the act during masturbation.
More extreme variations of anal fisting include double-fisting, punch-fisting and moving the fist in and out of the anus.
Anal fisting is sometimes referred to as handballing or fist fucking.
