Rectal fist insertion. An unusual form of sexual behavior.
Shook LL, Whittle R, Rose EF.
Rectal fist insertion (fist fucking) is an uncommon and potentially dangerous sexual practice. This is usually a homosexual activity, but can also be a heterosexual or an autoerotic practice. One known death has been reported associated with rectal fist insertion, in which the complications of anal and colonic tears and bleeding had occurred (see Editor's note). The possibility of drug overdose is also probable, as drugs and alcohol are commonly introduced into the rectum to promote sphincter relaxation and to ease the discomfort of anal dilatation.
