From a #1 Apple podcast host, Lambda Literary fellow, and dominatrix comes a sex-positive, judgment-free cultural deep-dive into the world of kink. When celebrated BDSM educator Tina Horn first launched Why Are People Into That?!, publications from Vice to Buzzfeed heralded it as one of the best sex podcasts around. Each episode centered around a different fetish or fantasy, thoughtfully examining why, exactly, different strokes work for different folks. From sex workers and scientists to artists and activists, Tina's wide range of guests helped educate fascinated listeners across the world on the wide spectrum of humanity's appetites. With her listeners growing more and more insatiable, she soon realized that the only way to address the titular question with all the depth and nuance it deserved was to turn that idea into a book. From spanking, strap-ons, and sluts, to taboos involving cake, chains, and cannibalism, WHY ARE PEOPLE INTO THAT? explores the universal drives that shape even the most specific erotic tastes, and the cultural context that molds and is molded by the way we conceptualize pleasure, gender, fantasy, and power. With buoyant prose, Tina invites us to reconsider everything we thought we knew about sexuality. How, for example, should we think about "consensual nonconsent" in a post-#MeToo era? How does cross-dressing fit in with our evolving cultural understanding of gender performance and identity? And what do foot fetishists, fisters, and FinDoms have in common? Blending insightful cultural criticism, investigative journalism, and spicy anecdotes from Tina's 15+ years of hard-earned expertise in the sex industry and beyond, WHY ARE PEOPLE INTO THAT? is a philosophical-but-fun exploration of the prismatic spectrum of human desire and the expansive possibilities of pleasure. For fans of adrienne maree brown and Emily Nagoski, this raunchy and rousing book is perfect for anyone who is interested not only in the intricacies of what we desire, but in how desire itself really works.
