With all the latest information, this new fifth edition of The Puberty Book answers all of those direct (pre) teenage questions: What s a wet dream? How do you ask a girl on a date? How are sperm made? After sex do you get sick? What do you do if your penis is small? How does milk get into breasts? When should you start shaving your legs? With simple language and honest answers, the authors discuss the changes that happen at puberty - sex and sexuality, health, relationships, pregnancy and birth.
