This book is directed at parents and teachers and should also be helpful to adolescent boys as a supplement to their courses or counseling in sex education. Besides acquainting the adolescent with the basic psychological and physical facts about sex, Dr. Gottlieb devotes a great portion of this text to purging the young man of various feelings of guilt to which, during puberty, he is particularly susceptible. From the first awareness of his sexuality, through various stages of fantasy and auto-eroticism, and finally to normal sexual activity, Dr. Gottlieb's chief aim is to assure while informing. Difficult subjects such as homo-sexuality and sexual experimentation are handled here with tact in this straightforward text illustrated with case histories. What a Boy Should Know About Sex will be particularly helpful to adults, who, in order to help their children develop, must avoid projecting their own misconceptions.
