Mr. Z. further says that he has not performed coitus in seven years; but he thinks he is potent. The riding was a perfect substitute for that “animal act,” even when ejaculation was not induced. For eight months Z. had determined to give up his masochistic play, and had kept his determination. But he thought that if a woman only half-way pretty were to address him directly, and say, “Come, I want to ride you,” he would not be strong enough to withstand the temptation. Z. wishes to know whether his abnormality is curable; whether he is unworthy as a vicious man, or an invalid deserving pity. The following case seems very similar:— Case 52. A man finds satisfaction in the following manner: Occasionally he goes to a puella publica. Here he has a porcelain ring, like those used in hanging curtains, put on his penis. Two cords are attached to the ring and drawn backward between his legs and attached to the bedstead. Then he tells the woman to beat him mercilessly with a whip and cry “whoa” to him constantly, and treat and abuse him as if he were an unruly horse. The more the woman spurs him on to pull, with shouts and blows, the greater his sexual excitement becomes. Erection occurs (probably mechanically favored by compression of the dorsal vein of the penis, which, when the cords are strained, must be closed by the pressure of the hard ring). With increasing erection, the whole member is compressed by the ring, and finally ejaculation occurs, with lustful feeling. Even in the foregoing series of cases, with other things, the act of being walked upon has played a _rôle_ as a means of expressing the masochistic situations of humiliation and pain. The exclusive and most extensive use of this means for perverse excitation and satisfaction is shown in the following classical case of masochism, which Hammond reports (_op. cit._, p. 28) from an observation by Dr. Cox,[64] of Colorado:— Case 53. X., a model husband, very moral, the father of several children, has times—_i.e._, attacks—in which he visits brothels, chooses two or three of the largest girls, and shuts himself up with them. He bares the upper portion of his body, lies down on the floor, crosses his hands on his abdomen, closes his eyes, and then has the girls walk over his naked breast, neck, and face, urging them at every step to press hard on his flesh with the heels of their shoes. Sometimes he wants a heavier girl, or some other act still more cruel than this procedure. After two or three hours he has enough. He pays the girls with wine and money, rubs his blue bruises, dresses himself, pays his bill, and goes back to his business, only to give himself the same strange pleasure again after a few weeks.
