Out in Time explores the life experiences of three generations of gay men -- the Stonewall, AIDS, and Queer generations--arguing that while there are generational differences in the lived experiences of young gay men, each one confronts its own unique historical events, realities, and socio-political conditions, there are consistencies across time that define and unify the identities of gay men. Based on interviews with 15 gay men from three generations and various ethnic and class backgrounds, this book offers individual stories to humanize existing research on gay male identity formation and health behaviors. The result is an accessible introduction to the lives of gay men and the ways gay coming of age has changed or remained consistent over the course of the last 50 years. The book will be most useful to the general reader or early undergraduate, who can better make sense of existing research with the anecdotal illustrations this book provides. Halkitis emphasizes that identifying oneself as a gay man (that is, coming out) is not a singular act but an ongoing process that, although specific circumstances have changed over time, is consistently necessitated by the dominant society's assumptions that everyone is heterosexual until proven otherwise, and by its macro- and microaggressions against LGBTQ individuals.
