Hundreds of thousands of straight American men have had sex with multiple men. Not all are closeted gay or bisexual men. Nor are they all just experimenting. This book examines the stories of sixty such men in rural areas and small towns across the Pacific Northwest, the Mountain West, and the Midwest. They identified as straight primarily because they are embedded in institutions and communities that reward male heterosexuality and masculinity. The author refers to all of this as “straight culture.” Most identified as straight not because they hated gay or bisexual men. Instead, they felt that most aspects of their lives were heterosexual. Those married to women wanted to stay that way and saw their role as a husband as key to their straightness. They considered their sex with men mostly irrelevant to their identity. All described themselves as masculine, too, and many felt that identifying as gay or bisexual would have threatened their masculinity. Wanting to avoid discrimination and enjoying being part of a socially dominant group played roles as well. Most of these men were also primarily or exclusively attracted to women. Many began having sex with men only later in life to continue having sex but without feeling as though they were cheating on their wives. The stories of the men interviewed are filled with irony and paradox yet are also genuine. Overall, the book explores this question: What if heterosexuality, and particularly male heterosexuality, is not always what it seems?
