This is a wonderful book that keeps humor in "the talk."
I am surprised by how many reviewers here oppose the sex theory in favor of the stork theory. Apparently, they never knew people needed to have sex to have babies. "How shocking! How offensive! And there're pictures of human body parts?" Do these people blindfold their children when it's bath time?
Look, if you're not an ignorant nematode, this is the book you've been looking for to give a good overview of sex and to keep your children from growing into sexually dysfunctional Amazon review trolls.
