Kraft-Ebing managed to get all of 19th century freakdom in only 600 pages, imagine if he had internet!
Case 98. A lady told Dr. Gemy that in the bridal night and in the night following her husband contented himself with kissing her, and running his fingers through the wealth of her tresses. He then fell asleep. In the third night Mr. X. produced an immense wig, with enormously long hair, and begged his wife to put it on. As soon as she had done so, he richly compensated her for his neglected marital duties. In the morning he showed again extreme tenderness, whilst he caressed the wig. When Mrs. X. removed the wig she lost at once all charm for her husband. Mrs. X. recognised this as a hobby, and readily yielded to the wishes of her husband, whom she loved dearly, and whose libido depended on the wearing of the wig. It was remarkable, however, that a wig had the desired effect only for a fortnight or three weeks at a time. It had to be made of thick, long hair, no matter of what colour.
The result of this marriage was, after five years, two children, and a collection of seventy-two wigs.
