Sex Explained: Honest Answers to Your Questions about Guys and Girls, Your Changing Body, and What Really Happens During Sex

I have this book in my middle school library. It's constantly being read by students who don't feel comfortable asking adults their questions about puberty and sexuality. I would rather a teenager get facts from a book written by a professional than rely upon what passes for information in school locker rooms and internet chat rooms. For their own safety, mental health, and physical health's sake, knowledge of the human body cannot be considered taboo. Books are safe places to explore ideas and satisfy curiosity and questions, and this book answers many of the questions people have in a non-threatening, honest way. Those who find this book too intense for their tastes may choose the lauded "It's Perfectly Normal" by Robbie Harris, which is recommended for grades 3-8. This one I would put at grades 7-9.
