Gender Circuits

be a useful addition to anyone’s bookshelf. In the first chapter, sexuality is introduced as more than just the biological act of sex. Instead, the authors describe how sexuality is a fluid concept that has changed over time as humans have evolved both physically and societally. Later chapters describe sex specifics in both male and female bodies, leading to a discussion of sex, gender, and transgender individuals. Two chapters are given to sexuality throughout the life span, and several more chapters address sexual orientation, atypical sexuality, and sexual disorders. Potentially negative aspects of human sexuality are also discussed, including disease and assault. Visually, the pages in Discovering Human Sexuality are equally covered in well written text and helpful images, including photographs, historically relevant pictures, and anatomical diagrams. If six hundred pages was not enough, the book has a companion website, complete with summaries, study questions, and online activities. What is truly impressive about Discovering Human Sexuality is the positivity with which the authors approached the presented topics. Unsurprisingly, the text is written in a highly sex positive way, which allows it to remain informative while dealing with subjects that may make readers uncomfortable at times. The unbiased manner in which the authors discuss sexual positions or group relations allows the text to be instructive, yet nonjudgmental. It is clear that the authors put effort into being inclusive of the diversity that exists in human experiences. Thus, this textbook is an ideal resource for the variety of students enrolled in a college course on human sexuality. Overall, the interdisciplinary collaboration of LeVay, Baldwin, and Baldwin has produced a comprehensive guide, and generally good read, to one of the most pervasive aspects of human nature.
