Research has found that in psychogenic sexual disorders, cognitive processes are more important than physiological ones. Negativistic “thinking” about one’s sexual activity aggravates the symptom and perpetuates it. Therefore, as vital as a differential diagnosis of sexual dysfunction is, the uncovering of Negative Self-Hypnosis (NSH) becomes essential for the successful resolution of the sexual problem. NSH constitutes the “hidden symptom” in all psychogenic sexual dysfunctions. After explicating NSH, the paper offers specific hypnotic techniques for different sexual disorders.
