Book excerpt: "Since the 1970s, health professionals, researchers, governments, advocacy groups, and commercial interests have invested in the pursuit of something called 'sexual health'. Programs were launched, organizations founded, initiatives funded, products sold-and yet, no book before this one asks: What does it mean to be sexually healthy? When did people conceive of a form of health called sexual health? And how did it become the gateway to addressing a host of social harms and the reimagining of private desires and public dreams? Offering an entryway into the distinctive worlds of sexual health, this book traverses the distance from the research and treatment domains where sexual health is assessed, measured, and improved to the "sex expos" that invite attendees to "leave their inhibitions at the door and explore today's top intimacy products" and beyond. Sexual health encompasses wildly disparate agendas and speaks to innumerable concerns-from sexual dysfunction to sexual violence, from HIV prevention to reproductive freedom, to the practicalities of sexual contact during a global pandemic. Rather than a thing apart, sexual health is intertwined with nearly every conceivable topical debate-and more of them every day. Through his wide-ranging exploration, Steven Epstein provides the critical tools needed to bring into focus the different faces of sexual health and parse the debates that swirl around it"--
