After about a year and a half of sexual intercourse with this girl, his love for her grew cold, because he did not find her so “fine and pure” as he wished. From this time it was necessary for him to call upon ideas about boots for help, which had been latent, in order to be potent in sexual intercourse with her. In proportion as his power failed, these ideas arose spontaneously. Thereafter he had coitus with other women. Now and then, especially when the woman was in sympathy with him, the act took place without any assistance of imagination. It once happened that the patient committed a rape. It is remarkable that on this single occasion he had a pleasurable feeling in the (forced) act. Immediately after the deed he had a feeling of disgust. When, an hour after the forced indulgence, he had coitus with the same woman, with her consent, he experienced no feeling of pleasure. With decrease of virility,—_i.e._, when it was preserved only in connection with ideas about boots,—libido for the opposite sex decreased. The patient’s slight libido and weak inclination for women are evidenced by the fact that, while he still sustained sexual relations with the peasant girl, he began to masturbate. He learned the vice from “Rousseau’s Confessions,” the book accidentally falling into his hands. The boot-fancies immediately linked themselves with corresponding impulses. He then had violent erections, masturbated, and ejaculation afforded him a lively feeling of pleasure, which was denied to him in coitus; and at first he felt himself fresher and brighter, as a result of the masturbation. In time, however, symptoms of sexual, and, later, of general, neurasthenia, with spinal irritation, appeared. He then at first gave up masturbation, and sought his first love; but she was now more than ever indifferent to him. Since he finally became impotent, even when he called ideas of boots to his assistance, he gave up women entirely, and again practiced masturbation; by which he felt himself protected from the impulse to kiss and blacken servants’ boots. At the same time, he continued to feel that his sexual position was a painful one. He again occasionally attempted coitus, and was successful in it as soon as he thought of blackened boots. Too, after continued abstinence from masturbation, he was sometimes successful in coitus without any artificial aid. The patient says that his sexual needs are intense. If he has not had an ejaculation in a long time, he becomes congestive and psychically much excited, and tormented by repugnant images of boots, so that he is forced to have coitus, or, preferably, to masturbate.
