5. In reading Sacher-Masoch, it struck me that in masochists, now and then, there was also an undercurrent of sadistic feeling. Too, I have now and then discovered in myself sporadic feelings of sadism. I must remark, however, that the sadistic feelings are not so marked as the masochistic; and that, aside from the fact that they are infrequently accessory, the sadistic fancies never leave the sphere of abstract feeling, and, above all, never take the form of concrete, connected ideas (like those above mentioned). The effect on libido, however, is the same with both. If this case is remarkable on account of the complete development of the psychical state that constitutes masochism, the following one is noteworthy because of the great extravagance of the acts resulting from the perversion. The case is also particularly suited to make clear the reason for the subjection and humiliation at the hands of the woman, and the peculiar sexual coloring of the resulting situations:— Case 51. _Masochism._—Mr. Z., official, aged 50; tall, muscular, healthy. He is said to come of healthy parentage, but his father was thirty years older than his mother. A sister, two years older than Z., suffers with delusions of persecution. There is nothing remarkable in Z.’s external appearance. Skeleton entirely masculine; abundant beard, but no hair on trunk. He characterizes himself as a man of sanguine temperament, whom no one can depress; though irascible and quick-tempered, he is quick to regret outbursts. Z. says he has never masturbated. From his youth there have been nightly pollutions, in which girls play a part; but the sexual act, never. For example, he dreams that a pleasing woman lies heavily on him, or that, as he lies sleeping on the grass, she playfully walks up his back. Z. had always been averse to coitus with a woman. This act seemed animal to him. Nevertheless, he was drawn to women. It was only in the society of beautiful women and girls that he felt well and in his place. He was very gallant without being forward.
