In 1966 William H. Masters and Virginia E. Johnson published their landmark study, Human Sexual Response, one of the first books to report scientifically on a subject shrouded in taboo and prudery - a book that changed the way Americans think about sexuality and is often credited with helping to start the sexual revolution because of its bold, careful debunking of myths. Today, almost three decades later, critically important changes have occurred in the social, legal, political, scientific, medical, epidemiological, psychological, emotional, public, and private perspectives on sexuality. In Heterosexuality, the world's foremost trio of sex researchers and therapists - Masters, Johnson, and their longtime colleague, Robert C. Kolodny, M.D. - addresses these changes with a comprehensive, definitive, and up-to-date survey of virtually every aspect of the sexual relations between women and men. Here, for the first time ever, is Masters, Johnson, and Kolodny's practical program of exercises for all those seeking to enhance their responsivity or deal with a sexual problem without the aid of a therapist. Sexuality is the source and arena of some of the deepest joys men and women share, and some of the deepest vulnerabilities. Writing with candor and sensitivity, Masters, Johnson, and Kolodny provide the best, most sensible, and most useful information on topics as diverse as sexual response and sexuality, love and intimacy, performance anxiety, male and female sexual dysfunction, compulsive sexual behavior, sexual and reproductive health, conception, contraception, fertility, HIV and AIDS, teenage sexuality, sex and aging, and extramarital affairs. Heterosexuality cuts through the platitudes and media hype to delve deeply into the sexual psyche, promoting, a fuller and richer understanding of male-female sexuality for the general public, and for social scientists, mental health professionals, and medical practitioners.
