This book barely skims the surface of the topic, but it skims it well. But it's not enough to answer the larger, underlying question of what sex actually is. It's incomplete, and it reads more like a meditation on the process of talking to children about sex than an actual instructive book. I would love to see a thorough, detailed book about sex written in this style. It drew me in through its conversational tone, but left me wanting something more substantial. The artwork is great, as well.

Sex is wonderful, but it's personal, and it's something that everybody involved has to agree to.
