It's Perfectly Normal Book

Waaay to graphic for a 10 year old, or even a young teenager. All of the written work is very good and scientific. But I do not think a 10 year old should have a step by step description of the act of sex. Also, it seems to take the view that you will see many different naked people throughout your life. There were waaaaaaay to many cartoons of naked people. I was uncomfortable with it. I don't think there is anything wrong with only seeing your spouse and children naked. It was just to much. People were naked when they didn't need to be. Which takes away from the good writing. I also don't think you need cartoons of adults having sex. It just doesn't seem appropriate. If you are encouraging your children to wait to have sex until they are married, this is probably not the book for you.
