In a case that has been reported to me, somewhat similar ideas played a part. The subject is a tall, well-developed man, aged 28, delicate in childhood, but now normal in health and physical condition, though not fond of athletics. His mental ability is much above the average, especially in scientific directions; he was brought up in narrow and strict religious views, but at an early age developed agnostic views of his own. From the age of 6, and perhaps earlier, he practised masturbation almost every night. This was a habit which he carried on in all innocence. It was as invariable a preliminary, he states, to going to sleep as was lying down, and at this period he would have felt no hesitation in telling all about it had the question been asked. At the age of 12 or 13 he recognized the habit as abnormal, and fear of ridicule then caused him to keep silence and to avoid observation. In carrying it out he would lie on his stomach with the penis directed downward, and not up, and the thumb resting on the region above the root of the penis. There was desire for micturition after the act, and when that was satisfied sound sleep followed. When he realized that the habit was abnormal he began to make efforts to discontinue it, and these efforts have been continued up to the present. The chief obstacle has been the difficulty of sleep without carrying out the practice. Emissions first began to occur at the age of 13 and at first caused some alarm. During the six following years indulgence was irregular, sometimes occurring every other night and sometimes with a week's intermission. Then at the age of 19 the habit was broken for a year, during which nocturnal emissions took place during sleep about every three weeks. Since this, shorter periods of non-indulgence have occurred, these periods always coinciding with unusual mental or physical strain, as of examinations. He has some degree of attraction for women; this is strongest during cessation from masturbation and tends to disappear when the habit is resumed. He has never had sexual intercourse because he prefers his own method of gratification and feels great abhorrence for professional prostitutes; he could not afford to marry. Any indecency or immorality, except (he observes) his own variety, disgusts him. At the earliest period no mental images accompanied the act of masturbation. At about the age of 8, however, sexual excitement began to be constantly associated with ideas of being whipped. At or soon after this age only the fear of disgrace prevented him from committing serious childish offenses likely to be punished by a good whipping. Parents and masters, however, seem to have used corporal punishment very sparingly.
