But it's literally the defecation hole. The top/seme gets feces and blood on his dick while the bottom/uke gets cum in his ass mixed in with the shit and blood while his butt muscles are damaged and permanently worn out (eventually to the point of incontinence), and they risk spreading all kinds of parasites and viruses, all while the whole room stinks like shit every time they do it, for no other reason than for a guy to use another guy's excretion hole to masturbate with and/or intentionally violate and/or humiliate said guy at the risk of his own health, making a complete mockery of human reproduction. Anal "sex" is unironically as bad as hard drugs are.
