In the 1970s a group of pioneering feminist entrepreneurs launched a movement that ultimately changed the way sex was talked about, had, and enjoyed. Boldly reimagining who sex shops were for and the kinds of spaces they could be, these entrepreneurs opened sex-toy stores like Eve’s Garden, Good Vibrations, and Babeland not just as commercial enterprises, but to provide educational and community resources as well. In Vibrator Nation Lynn Comella tells the fascinating history of how these stores raised sexual consciousness, redefined the adult industry, and changed women's lives. Comella describes a world where sex-positive retailers double as social activists, where products are framed as tools of liberation, and where consumers are willing to pay for the promise of better living—one conversation, vibrator, and orgasm at a time.

Karl Ulrichs's studies of sexual diversity galvanized the burgeoning field of sexual science in the nineteenth century. But in the years since, his groundbreaking activism has overshadowed his scholarly achievements. Ulrichs publicly defied Prussian law to agitate for gay equality and marriage, and founded the world's first organization dedicated to the legal and social emancipation of homosexuals. Ralph M. Leck returns Ulrichs to his place as the inventor of the science of sexual heterogeneity. Leck's analysis situates sexual science in a context that includes politics, aesthetics, the languages of science, and the ethics of gender. Although he was the greatest nineteenth-century scholar of sexual heterogeneity, Ulrichs retained certain traditional conjectures about gender. Leck recognizes these subtleties and employs the analytical concepts of modernist vita sexualis and traditional psychopathia sexualis to articulate philosophical and cultural differences among sexologists. Original and audacious, Vita Sexualis uses a bedrock figure's scientific and political innovations to open new insights into the history of sexual science, legal systems, and Western amatory codes.
