This important book provides unique new knowledge on the lived experience of openly bisexual men without medicalizing or pathologizing them. Presenting research from sexology, sociology, and psychology, it features extensive findings on the sexual, social, romantic, and emotional behaviors of the 90 men interviewed in the U.S. and U.K. Issues and challenges are examined in such areas as identity and self-concept, along with the burden of social erasure and the paradox of stigma from both the gay and straight communities. However, the research reveals evidence of a recent cultural transition toward acceptance of bisexual identity and behavior, with younger bisexual men experiencing better social lives and increased recognition of the legitimacy of bisexuality. Among the topics covered: Examining the components of sexuality. Measuring and surveying bisexuality. Bisexual burden Demonstrating a generational cohort effect Expansion of gendered boundaries. Erosion of the one-time rule of homosexuality. Coming out in the 21st century. Bringing clarity and focus beyond the gender binary—and compelling insights into why society and science have trouble shedding that paradigm—The Changing Dynamics of Bisexual Men’s Lives will interest sexuality scholars, sexologists, and social scientists studying the social aspects of sexuality.
