In a case of Moll's the development of a youthful admiration for the nates in a coprolagnic direction may be clearly traced. In this case a young man, a merchant, in a good position, sought to come in contact with women defecating; and with this object would seek to conceal himself in closets; the excretal odor was pleasurable to him, but was not essential to gratification, and the sight of the nates was also exciting and at the same time not essential to gratification; the act of defecation appears, however, to have been regarded as essential. He never sought to witness prostitutes in this situation; he was only attracted to young, pretty and innocent women. The coprolagnia here, however, had its source in a childish impression of admiration for the nates. When 5 or 6 years old he crawled under the clothes of a servant girl, his face coming in contact with her nates, an impression that remained associated in his mind with pleasure. Three or four years later he used to experience much pleasure when a young girl cousin sat on his face; thus was strengthened an association which developed naturally into coprolagnia. (Moll, _Untersuchungen über die Libido Sexualis_, bd. i, p. 837.) It is scarcely necessary to remark that an admiration for the nates, even when reaching a fetichistic degree, by no means necessarily involves, even after many years, any attraction to the excreta. A correspondent for whom the nates have constituted a fetich for many years writes: "I find my craving for women with profuse pelvic or posterior development is growing and I wish to copulate from behind; but I would feel a sickening feeling if any part of my person came in contact with the female anus. It is more pleasing to me to see the nates than the mons, yet I loathe everything associated with the anal region." Moll has recorded in detail a case of what may be described as "ideal coprolagnia"--that is to say, where the symbolism, though fully developed in imagination, was not carried into real life--which is of great interest because it shows how, in a very intelligent subject, the deviated symbolism may become highly developed and irradiate all the views of life in the same way as the normal impulse. (The subject's desires were also inverted, but from the present point of view the psychological interest of the case is not thereby impaired.) Moll's case was one of symbolism of act, the excreta offering no attraction apart from the process of defecation. In a case which has been communicated to me there was, on the other hand, an olfactory fetichistic attraction to the excreta even in the absence of the person.
