This book is based on the premise that sexual expression is a way for people to show affection and love for one another. The book is divided into six chapters that cover topics related to sexuality and growing up. The sections in each chapter contain questions that preteens and teenagers typically ask and provide clear, unambiguous, and comprehensive answers to the questions. Within each section, the questions are given roughly in order of progressing complexity and sophistication. Chapter 1 of the book addresses bodily development and sexual maturation, including sections on development, sexual characteristics and their development, forms of sexual activity, male and female sexual development and function, and menstruation and the menstrual cycle. Chapter 2 explains conception, pregnancy, and childbirth. Chapter 3, which addresses issues of relationships, contains sections on family relationships, emerging sexual identity, and sexual expression and sexual relationships. The topic of birth control is discussed in chapter 4. Chapter 5 provides answers to general questions about sexually transmitted diseases, and to specific questions about AIDS and about other particular sexually transmitted diseases. Chapter 6 considers the topic of heredity. A glossary of terms, including slang and street terms, is provided. (BC)
