Query: Wonderful book - lots to discuss with my child

My 11 year old has completely enjoyed this book. When I learned he was going to have sex ed in school in 5th grade, I wanted him to be properly informed ahead of time, and to not be embarrassed to ask questions etc.. We have had many wonderful discussions at home as a direct result of his reading this book and he feels free to ask me questions and discuss topics that I didn't previously know how to approach. I highly recommend this book.Anyone know where the expression the birds and the bees originated?
