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.
直肠瘘插入（直肠性交）是一种罕见且有潜在危险的性行为。这通常是一种同性恋行为，但也可能是异性恋或自慰行为。据报道有一例已知的与直肠瘘插入相关的死亡案例，其中出现了肛门和结肠撕裂及出血的并发症（见编者注）。药物过量的可能性也很大，因为药物和酒精通常会被引入直肠以促进括约肌松弛并减轻肛门扩张的不适感。
