Love and Sex in Plain Language, fourth edition, by Eric W. Johnson (Harper & Row: $12.95).
This sensible guide to sex education is now in its fourth edition. Eric W. Johnson writes simply enough for a 10th grader to understand, but includes enough information--enhanced with charts of anatomy and pertinent diagrams--to hold value even for many knowledgeable adults.
"Sex is power," Johnson observes, but it must be combined with self-respect, communication and consideration for others to result in both physical pleasure and psychological satisfaction.
Avoiding both the coldly clinical approach and birds-and-bees coyness, Johnson covers all aspects of reproduction. His chapter on fertilization, pregnancy and birth is a gem. Sections on the main forms of contraception include a reliability chart, and sexually transmitted diseases are dealt with forthrightly.
