CASE 12.--Y., twenty-five years of age, homosexual, with a special preference for soldiers. In early childhood he noticed in himself a great fondness for handsome men. When walking in the streets of the town as a small boy, it was the soldiers, in especial, from among the men he met, who made a strong impression upon him. He remembers that when he was seven years of age, he allowed a soldier to take him on his knees, and that it gave him great pleasure to stroke the man's cheeks. The roughness of the cheeks gave him an extremely agreeable sensation, and he sought every opportunity of renewing this sensation. He found cavalry soldiers especially stimulating. From the age of eleven dates his peculiar delight in the well-rounded nates of a cavalry soldier. As he himself puts it, with the lapse of time, this has become to him a genuine fetich. Subsequently, young men-servants also aroused his interest, but never to the same degree as cavalry soldiers. The homosexual tendency has persisted into adult life. CASE 13.--Z., twenty-seven years of age, has several times been prosecuted, on account of his attempts to spy upon women in public lavatories. It is his custom, when in such a place he can observe the genital organs of a woman in the act of defaecation, to masturbate. He states that this tendency was well marked in him at the age of thirteen years. He believes, indeed, that at this time he was inspired mainly by curiosity--by a desire to see what the genital organs of a female were like. But he recalls that when a child, at about the age of eight or nine years, he experienced sexual stimulation when a girl cousin of six sat on his face; and he thinks that when only five or six years old he crawled under the petticoats of a servant girl, in order to lay his face against her nates. Even as early as this he experienced great pleasure in the act. CASE 14.--X., is now twenty years of age. He always experiences sexual excitement when he thinks of the act of whipping. It is unnecessary for him to play any active part in this himself; and it is a matter of indifference to him whether a man beats a woman, a woman beats a man, or an adult of either sex beats a child. In all cases alike the sight induces sexual excitement; and the imaginative reproduction of such a scene is his customary stimulus during masturbation--this being a fairly frequent occurrence. He traces back to childhood the stimulus exercised on him by a whipping seen or imagined. When from seven to nine years of age, he began to find such experiences sexually stimulating; by the age of ten, he was quite clear as to the existence of this peculiarity in himself. At this early age he struck himself with a stick, under the influence of an obscure impulse to arouse voluptuous sensations by means of the blows; he did this fairly frequently.
