I bought this book for my 12 year old son. I found the majority of the book acceptable, entertaining and informative . However the book also had sections geared towards older teens (I assume). I was surprised to find information regarding who should bring the condom on the date and other sexual issues. The book states that wether or not teens should be sexually active is not a topic of this book but if you are sexually active it is beyond rude to....and goes on to list a number of sexual situations.I was hoping to share this book with my son as I think he could benefit from it. However, I'll be putting it aside until I feel we have discussed some of the sexual issues addressed by the book and he is mature enough to handle it.It's too bad because I think he'd be more likely to want the other information now while he is excited about starting junior high and wanting to be treated as an adult.I
