In psychopathic individuals, sexually hyperæsthetic, as a result of this, it actually happens that the dressed woman is always preferred to the nude female form. It may be recalled that in Case 48 the woman was not to take off a garment, and that in Case 51, _equus eroticus_, the woman was preferred dressed. In Case 89, of the sixth edition,—that of a man manifesting contrary sexuality,—the same preference is expressed. Dr. Moll (_op. cit._) mentions a patient who could not perform coitus with puella nuda; the woman had to have on a chemise, at least. The same author (_op. cit._, p. 129) mentions a man affected with contrary sexuality, who was subject to the same dress-fetichism. The reason for this phenomenon is apparently to be found in the mental onanism of such individuals. In seeing innumerable clothed forms, they have cultivated desires before seeing nudity.[99] A more marked form of dress-fetichism is that in which, instead of the dressed woman, a certain kind of attire becomes a fetich. One can understand how, with an intense and early sexual impression, combined with the idea of a particular garment on the woman, in hyperæsthetic individuals, a very intense interest in this garment might be developed. Hammond (_op. cit._) reports the following case, taken from Roubaud (“Traité de l’impuissance,” Paris):— Case 81. X., son of a general. He was raised in the country. At the age of fourteen he was initiated into the joys of love by a young lady. This lady was a blonde, and wore her hair in ringlets; and, in order to avoid detection in sexual intercourse with her young lover, she always wore her usual clothing,—gaiters, a corset, and a silk dress. When his studies were completed, and he was sent to a garrison where he could enjoy freedom, he found that his sexual desire could be excited only under certain conditions. A brunette could not excite him in the least, and a woman in night-clothes could stifle every bit of love in him. In order to awaken his desire, a woman had to be a blonde, and wear gaiters, a corset, and a silk dress,—in short, she had to be dressed like the lady who had first awakened his sexual desire. He was always compelled to give up thoughts of matrimony, because he knew he would be unable to fulfill his marital duty with a woman in night-clothes.
