A Jewish patient was disowned by her family because one of her two marriages was to a Christian. Both husbands, one twenty years her senior, the other two years her junior, were impotent. She began treatment after the collapse of her first marriage. Her oral fantasies and fears of abandonment were intense. She had been suckled until the age of four and used to sit in a chair to suck her mother's breasts. Her genital impulses were related to great dependency and to an inability to tolerate frustration. A sado-masochistic concept of coitus and fantasies of oral impregnation underlay her phobia. These fantasies were experienced in the transference as well as in her 'phobic paranoid mechanisms' and in her feelings of being unwanted. Her phobia—she had had no sexual intercourse in four years of marriage—arose out of her relationship with love objects and her compulsive necessity to control them.
