Are dominance and submission inevitable in human relationships? Believing that sadomasochism is becoming an ever more obtrusive phenomenon in developed countries, the author surveyed 48 self-declared sadomasochists (43 male, 5 female) and 35 controls (26 male, 9 female) in an effort to elicit information on early family relationships, morale, and sexual behavior and fantasy; she also looks at the philosophy of masochism and its damaging effects.
