In the United States, sex education is more than just an uncomfortable rite of passage: it's a political hobby horse that is increasingly out of touch with young people's needs. In Touchy Subject, philosopher Lauren Bialystok and historian Lisa M. F. Andersen unpack debates over sex education, explaining why it's worth fighting for, what points of consensus we can build upon, and what sort of sex education schools should pursue in the future.

Andersen surveys the history of school-based sex education in the United States, describing the key question driving reform in each era. In turn, Bialystok analyzes the controversies over sex education to make sense of the arguments and offer advice about how to make educational choices today. Together, Bialystok and Andersen argue for a novel framework, Democratic Humanistic Sexuality Education, which exceeds the current conception of "comprehensive sex education" while making room for contextual variation. More than giving an honest run-down of the birds and the bees, sex education should respond to the features of young people's evolving worlds, especially the digital world, and the inequities that put some students at much higher risk of sexual harm than others. Throughout the book, the authors show how sex education has progressed and how the very concept of "progress" remains contestable.
