The men interviewed interpreted sex with men as compatible with heterosexuality and masculinity. What the author calls “bud-sex” is the way rural and small-town, white, straight men interpret or engage in sex in ways that reinforce their heterosexuality and masculinity. While the sex these men have with other men involves acts similar to those between gay and bisexual men, the meanings they attach to these acts differ greatly. Bud-sex has three components. First is hooking up with other masculine, white, and straight or bisexual men. Second is having secretive, nonromantic sex. And third is interpreting male-male sex as largely unthreatening to masculinity, heterosexuality, or marriage. Bud-sex, with its unique understandings of gender and sexual identity, reflects and reinforces the men’s embeddedness in straight culture. Sexual identity and masculinity depend on what sex acts mean, rather than on mere mechanics. Consequently, interpretations of sexual practices, not sexual practices in and of themselves, are crucially important. For the straight men interviewed, their interpretations both reflected and reinforced their embeddedness in straight culture. Bud-sex allows straight men to enjoy male-male sex without threatening either their heterosexuality or their masculinity.
