First published in English in 1929, "Sadism and Masochism "remains one of the most important books of sexology, a masterwork of psychoanalysis documenting and defining the spectrum of fetishes and psychosexual disorders. The culmination of research by Wilhelm Stekel, a psychologist who was an early follower of Freud, "Sadism and Masochism "describes some of the most disturbing, violent, and extreme instances of sexual perversion ever recorded. The sixty-four case histories reprinted here include such paraphilias as vampirism; cannibalism; necrophilia; castration and amputation complexes; genital mutilation; bestiality; impalement fantasies; crucifixion complexes; urolagnia and coprophilia; anal fetishes; and whippings, beatings, and blood. This new translation is an accessible, streamlined edition that presents the case histories in an approachable format for scholars and others curious about the dark and myriad list of human sexual behaviors.
