At the very beginning of Sexplanations, eight years ago, I stood in front of a dry erase board in one of the first classrooms I'd ever taught in. It was this delicious experience for me that also that ended up really popularizing Sexplanations. People got to learn for the first time about the clitoral hood, crura, and smegma. They realized how awful so-called sex education is in most of the world and how valuable it can be to stay curious.
