The impulse to beat others was never very strong. The patient experienced more satisfaction in filling his imagination with scenes of whipping. He never indulged in any other sadistic acts, and never had any desire to see blood, etc. Until his fifteenth year his sexual indulgence consisted of onanism, indulged in after such fancies. After that (dancing lessons, association with girls), the early fancies disappeared almost entirely, and were accompanied by but weak lustful feelings; so that the patient gave them up entirely. In their place came thoughts of coitus in a natural way, without anything sadistic. The patient indulged in coitus for the first time “on account of his health.” He then tried to abstain from onanism, but was not successful, though he often indulged in coitus, and with more pleasure than he had in onanism. He wished to be freed from onanism as something vicious. He had coitus once a month, but masturbated once or twice every night. He was normal sexually, with the exception of the onanism. There was no neurasthenia; genitals normal. Case 39. P., aged 15, of high social position, came of an hysterical mother, whose brother and father died in an asylum. Two children of the family died, in early childhood, of convulsions. The patient is talented, virtuous, and quiet; but at times he is very disobedient, stubborn, and passionate. He has epilepsy, and practices onanism. One day it was learned that P., with money, induced a comrade of fourteen, B., to allow himself to be pinched on the arm, back, and thigh. When B. cried, P. became excited and struck at B. with his right hand, while with his left he made manipulations in the left pocket of his trousers. P. confessed that to maltreat his friend, of whom he was very fond, gave him peculiar delight; and that ejaculation while hurting his friend gave him much more pleasure than when he masturbated alone, (_v._ Gyurkovechky, “Pathol. und Therapie der männl. Impotenz.,” p. 80, 1889.) That in all these cases of sadistic abuse of boys there can be no thought of a combination of sadism and contrary sexual instinct, as often occurs (_v. infra_) in individuals of contrary sexuality, is shown—aside from the absence of all positive signs of it—by a study of the next group, where, in association with the object of injury,—animals,—the instinct for women is seen to appear repeatedly. (g) _Sadistic Acts with Animals._—In numerous cases, sadistically perverse men that are afraid of criminal acts with human beings, or that care only for the sight of the suffering of a sensitive being, make use of the sight of dying animals, or torture animals, to stimulate or excite their lust.
