The second case is that of a woman, thirty-five years of age, of a greatly tainted family. For some years past she had been in the initial stage of paranoia persecutoria. This sprang from cerebral neurasthenia, the origin of which was found to be sexual hyperexcitation. Since her twenty-fourth year she had been given to manu stupro, the result of a disappointment from a broken engagement. To appease her intense sexual excitement, she began the practice of manu stuprum and of mental erethism by fancying herself to be in concarnatione. The story of her youth reads as follows: At the age of six to eight years she conceived the desire to be whipped. She had never been whipped nor present when others were thus punished. Hence she cannot understand how she came to have this strange desire. With the idea of being whipped she had a feeling of actual delight. She pictured in her fancy how fine it would be to be whipped by one of her female friends. She never had any thought of being whipped by a man. She revelled in the idea only and never attempted any actual realization of her fancies, which disappeared after her tenth year of age. Here we have a young masochist whose ideas of humiliation are associated with her own sex. The reason for the patient’s fancy for female friends lay in the fact that the masochistic desire was present in the mind of the child before the psychic vita sexualis had developed and the instinct for the male awakened. Had the desire lasted until puberty the association of these ideas with the male would have been established. The ideas of humiliation of the masochistic sufferers are in the beginning often associated with their own sex. Not that they are in any way homosexual at the same time, but because genuine, complete masochism, being a hereditary taint, the feverish longing for submission begins in early youth at a time when the child is as yet unconscious of the difference of sex. Sometimes the masochistic tendency is not fully developed. The desire to suffer pain at the hands of the lover has only the end in view to increase the natural libido in congressu.
