It’s Perfectly Normal by Robert Harris

When young people have questions about sex, real answers can be hard to find. Providing accurate, unbiased answers to nearly every imaginable question, from conception and puberty to birth control and AIDS, It’s Perfectly Normal offers young people the information they need—now more than ever—to make responsible decisions and to stay healthy. Already used as a trusted resource in twenty-five countries around the world (and translated into twenty-one languages), It’s Perfectly Normal marks its tenth anniversary with a thoroughly updated edition that includes the latest information on such topics as birth control, hepatitis, HIV, and adoption, among others. This definitive new edition also reflects the recent input of parents, teachers, librarians, clergy, scientists, health professionals, and young readers themselves.
