"erotic rumination," and if this rumination took place at night she would sometimes masturbate, the contact of the bedclothes, she said, giving her the illusion of a man. In time this vague longing for the male gave place to more definite desires for a man who would love her, and, as she imagined, strike her. Eventually she formed secret relationships with two or three lovers in succession, each of these relationships being, however, discovered by her family and leading to ineffectual attempts at suicide. But the association of pain with love, which had developed spontaneously in her solitary dreams, continued in her actual relations with her lovers. During coitus she would bite and squeeze her arms until the nails penetrated the flesh. When her lover asked her why at the moment of coitus she would vigorously repel him, she replied: "Because I want to be possessed by force, to be hurt, suffocated, to be thrown down in a struggle." At another time she said: "I want a man with all his vitality, so that he can torture and kill my body." We seem to see here clearly the ancient biological character of animal courtship, the desire of the female to be violently subjugated by the male. In this case it was united to sensitiveness to the sexual domination of an intellectual man, and the subject also sought to stimulate her lovers' intellectual tastes. (_Archivio di Psichiatria_, vol. xx, fasc. 5-6, p. 528.) This association between love and pain still persists even among the most normal civilized men and women possessing well-developed sexual impulses. The masculine tendency to delight in domination, the feminine tendency to delight in submission, still maintain the ancient traditions when the male animal pursued the female. The phenomena of "marriage by capture," in its real and its simulated forms, have been traced to various causes. But it has to be remembered that these causes could only have been operative in the presence of a favorable emotional aptitude, constituted by the zoölogical history of our race and still traceable even today. To exert power, as psychologists well recognize, is one of our most primary impulses, and it always tends to be manifested in the attitude of a man toward the woman he loves.[73]
