The line between straight men having sex with men and "actual" homosexuality is under constant scrutiny, and for straight men, violence is a key element that imbues homosexuality with heterosexual meaning, or untangles hetero-erotic forms of homosexuality from the affective, political, and romantic associations with gay and lesbian life. Sometimes this violence takes the form of humiliation or physical force enacted by one straight man as he makes sexual contact with another; in other cases, it may take the form of two men fantasizing about sexual violence against women. In many cases, violence is a central part of the work of reframing homosexual sex as an act that men do to build one another's strength, or to build what I call "anal resilience," thereby inoculating one another against what they imagine are the sincere expressions of gay selfhood.
