This friendly book talks to teens in their own language, with emphasis on the subject that is foremost in the minds of just about every adolescent boy and girl: Sex. Separate chapters titled Boy Stuff and Girl Stuff describe body changes that occur during puberty, with frank and open explanations of male and female genitals, how they feel and how they function. Chapters that follow discuss typical teen problems, as well as those entirely new feelings that come with sexual development. Among them are, having a crush on that attractive boy or girl, coping with controlling parents, menstruation, dating and sexual activity, contraception, pregnancy, sexually transmitted infections, homosexual impulses, and generally surviving those difficult yet exciting teen years. Line drawings on most pages.
