A broad, sound survey of sexual expression and developmental psychology covers many of the instances from early childhood to marriage in which sex enters the picture and offers directives for making the best of these opportunities to promote healthy sexual attitudes. From the first a positive approach is stressed; if children don't bring up the topic at home, parents should do so themselves within as natural a context as possible. Material on first curiosity, a proper degree of modesty, adolescence, menstruation, masturbation, the development of love-sex feelings at various stages, personality problems (becoming the ""right"" person) and the relativity of sexual freedom- is frankly discussed and documented by case histories and typical examples of ways in which parents and children can be more open with each other. With the goal of dispelling many of the current fears and inhibitions about sex, this would nevertheless maintain a high degree of idealism and respect for individual privacy. Seeing the discussions in black and white may do a lot to help hitherto reluctant parents and the young adults who may have the chance to read it too.
