This guide will appeal to followers of surrement "Titeuf" because it deals with topics quite delicate ... (sexuality, anatomy ...) while preserving the humor that characterizes all BD titeuf. It takes on well known, that this book does not skimp on the words "raw" about sexuality, but that said, let's call a spade a spade! Some parents may be a little "shocked" quite explicit schemes and déconseilleront younger. But if one is quite open, we will understand that this book is perfect for children 9 years of age often do not find answers to questions that begin to bother them (come on, remember ... at their age ...). Personally I prefer they learn things in life through the "guide of sexual willy" in the course of the school, nearby their playmates, often themselves, although misguided ... In any case the children love and that is the most important.
