The treatment of the patient is directed to the attainment of normal coitus with normal desire, where possible; for it may be assumed that, with success in making his sexual life normal, the patient’s shyness and apprehensiveness, which cause him great annoyance, may be much easier removed. The treatment followed by me (Dr. Moll) during three months and a half was as follows:— 1. The patient, who had a great desire to be cured, was most strictly forbidden to give himself up to the perverse thoughts. Of course, I did not give him the foolish advice not to think of blows at all. The patient could not follow such advice, since the thoughts come to him without any act of his own, even when he accidentally reads the word “blow” (schlagen). I forbade him only ever to voluntarily give himself to such thoughts. I advised him more particularly to do everything in order to turn his ideas in another direction. 2. I allowed him, commanded him even, to think of nude women, because many nude females interested him, even though, as he thought, they did not excite him sexually. 3. I sought, by means of hypnosis—which was hard to induce—and suggestion, to fortify the patient in this as far as possible. All attempts at coitus were forbidden in order to save the patient from a discouraging result. Within two months and a half this treatment led to the result that, as the patient stated, the perverse ideas occurred much less frequently and were constantly retreating to the background; indeed, according to the patient’s statement, erections occurred with the thoughts of nude women, became more frequent, and often induced him to masturbate with the thought of coitus without the occurrence of any idea of blows. Erotic dreams occurred but infrequently. These were concerned sometimes with normal coitus, sometimes with blows.
