Case 80. _Hair-fetichism._ Mr. X., between thirty and forty years old; from the higher class of society; single. He says that he comes of a healthy family, but from childhood has been nervous, vacillating, and peculiar; that since his eighth year he has been powerfully attracted by female hair. This was particularly true in the case of young girls. When he was nine years old, a girl of thirteen seduced him. He did not understand it, and was not at all excited. A twelve-year-old sister of this girl also courted, kissed, and hugged him. He allowed this quietly, because this girl’s hair pleased him so well. When about ten years old, he began to have sensual feelings at the sight of female hair that pleased him. Gradually these feelings occurred spontaneously, and memory-pictures of girls’ hair were always immediately associated with them. At the age of eleven he was taught to masturbate by school-mates. The associative connection of sexual feelings and a fetichistic idea was already established, and always appeared when the patient indulged in evil practices with his companions. With advancing years, the fetich grew more and more powerful. Even false hair began to excite him, but he always preferred natural hair. When he could touch or kiss it, he was perfectly happy. He wrote essays and poems on the beauty of female hair; he sketched heads of hair and masturbated. After his fourteenth year he became so powerfully excited by his fetich that he had violent erections. In contrast with his early taste while a boy, he was now charmed only by luxuriant, thick black hair. He experienced intense desire to kiss such hair, particularly to suck it. To touch such hair afforded him but little satisfaction; he obtained much more pleasure in looking at it, but particularly in kissing and sucking it. If this were impossible, he would become unhappy, even to the extent of tædium vitæ. Then he would attempt to relieve himself, imagining fantastic “hair-adventures” and masturbating. Not infrequently, in the street and in crowds, he could not keep from imprinting a kiss on ladies’ heads. He would then hurry home to masturbate. Sometimes he could resist this impulse; but it was then necessary for him, filled with feelings of fear, to run away as quickly as possible, in order to escape the domination of his fetich. He was only once impelled to cut off a girl’s hair in a crowd. In the act he was seized with fear, and was not successful with his pocket-knife; and, by flight, he narrowly escaped detection.
