Every two weeks he does as follows: he lies down in bed dressed in his underclothes and defecates. Then he lies in his stools for several hours. After that he takes great pains to remove every trace. He washes the drawers and the shirt or he burns them up. At the baths, where he is always very excited sexually he does the same thing. He does that there more readily because the means are at hand for cleaning himself afterwards. He usually takes along a package of clean linen. At the public baths every cabin has a couch. He lies down and allows his bowels to move. There he lies feeling very satisfied and masturbates or has a spontaneous ejaculation. Then he bathes to clean himself and the package of soiled linen he throws into a river or anywhere where it disappears quickly. In these scenes he reproduces the infant in swaddling clothes. He even presses the covers tightly around him so that he cannot move, to give himself the illusion of being tied down. He repeats the infantile scenes of cleaning by the mother, during which in his fancy he plays the double role of mother and child. He struggles with greatest anxiety against this remarkable paraphila but always submits to it in the end. The longest interval up to the time of the psychoanalysis was four weeks. After that “orgy of filth,”—as he calls it—he feels depressed and is ashamed of himself. He has not mentioned this to a living soul and even the physician at the sanitarium knew nothing about it. He went through this act several times not at the sanitarium, but in his room because the baths were not private. When discussing sexual infantilism we shall learn of several similar cases. His attitude towards his mother is very changeable but not so emotionally tense as his relations with his father. He carries on a quiet and occasionally affectionate exchange of letters with his mother, but with his father, never. He is to a certain extent fond of his mother. As he tried masturbation in front of his father as a child so now he keeps nothing of his sexual life secret before me. He relates frankly everything. As a child he loved his mother very much and often wished to be with her. His mother is now an old woman, partially paralysed. Nevertheless he noticed during his last visit home that she is still a pretty woman and repeatedly felt impelled to approach her.... At such times he treats her very roughly and scornfully, and is inclined to make fun of her and her age. He has had repeatedly affairs with old women. At his last lodging place there was an elderly woman, whose face was badly wrinkled, with whom he became intimate but after a short time he sought a quarrel with her and moved out. That is the way he behaves with everybody. He quarrels over some trifle, becomes very excited and makes a terrible scene. Then he is through with that person for good.
