Masturbation also causes that form of increased erethism, connected with female impotency, in which the orgasm no longer occurs during the conjugal embrace. For this reason the victim prefers solitary indulgence even after marriage. In Moll’s case the woman, thirty years of age, mother of several children, is happily married, loves her husband and is loved in return. Yet coition does not gratify her in the least. She finds satisfaction only in solitary stupro manu by which orgasm is induced in the highest degree. In this way there are times, when the patient who is a modest, moral woman, practises autoeroticism several times a day. To this class of patients belong the cases recorded by Loiman, Laker, and others. The sexual functions were originally normal and satisfaction was possible in the normal way. Through excessive masturbation, however, the nerves became so weakened that normal coition did not give the desired satisfaction. In Troggler’s case the woman had practised autoeroticism excessively from her thirteenth year and found satisfaction fricando et trahendo clitoridem. When she began to have normal concarnatio at the age of eighteen, she found that she could not obtain satisfaction for her excessively increased voluptuous desire except manuali fricando clitoridis inter coitum. In Laker’s case of a married woman, twenty-four years of age, the patient never experienced the least satisfaction in concarnatione with her husband, while she found the desired effect in autoeroticism, especially in mutuo stupro manu. In another of the same author’s cases a woman of thirty-four years of age practised stuprum manu mutuum and found great satisfaction in this activity. At the age of nineteen she was married and in spite of mutual affection she could not experience any libido. This fact did not prevent her from giving birth to two healthy children. In another of Troggler’s cases, the woman, twenty-five years of age, was induced to practise autoeroticism when eleven years of age. On account of her increased sexual desires she began to have complexus venereus when fifteen years old. But she could not find the least satisfaction in congressu, although she practised it with a number of different men. Only stuprum manu offered her the desired libido.
