Dr. Franzblau's well-written book brings the findings of psychiatric research and therapy in the area of sex to the adult reader so that he may carry on his own life more fruitfully and lead his children to sexual maturity. He describes the growth of the child from birth as it meets frustration with compensation. The importance of the breast, mothering, the infant fantasies of omnipotence and exclusive possession of the mother (which reappear in love relationships), the effect of the coming of a second child on the firstborn, what to tell a child about sex, the result of the child's realization of sex differences, and the special approaches to feminine maturity all are covered. Various types of flight from fulfillment in the adult, and of lasting marriages which, although they may not be happy, must be considered good since they fill the need for both partners, are also discussed. Dr. Franzblau scores Dr. Kinsey on several counts, particularly on disregard of the unconscious. Here is the psychiatric side of the picture, somewhat streamlined but authoritative, and (for the unoriented) demanding reading.
