The Handbook of Clinical Sexuality for Mental Health Professionals, 3rd Edition, builds on the authors' authoritative first person voice on sexual matters of the previous editions. The work reflects the field's growing sophistication about sexual disorders and their therapies. The scope has been expanded to keep pace with new literature and research in the field, and eight additional chapters have been added. New topics include the politics of diagnosis, persistent genital arousal, asexuality, post orgasm illness, scientific findings concerning origin of orientation, and partnering with the pharmaceutical industry. Easily accessible, the Handbook is divided into sections that touch on fundamental knowledge and skills; treatment;　men's major sexual concerns; women's major sexual concerns; problems common to both genders; the diversity of sexual lives; and future and trending topics. Written in a personal, supervisory style, the book will help new therapists anticipate clinical contingencies and help experienced therapists refine their thinking and teaching.
