It is in masochism, or passive algolagnia, that we may most frequently find scatalogic symbolism in its fully developed form. The man whose predominant impulse is to subjugate himself to his mistress and to receive at her hands the utmost humiliation, frequently finds the climax of his gratification in being urinated on by her, whether in actual fact or only in imagination. In many such cases, however, it is evident that we have a mixed phenomenon; the symbolism is double. The act becomes desirable because it is the outward and visible sign of an inwardly experienced abject slavery to an adored person. But it is also desirable because of intimately sexual associations in the act itself, as a symbolical detumescence, a simulacrum of the sexual act, and one which proceeds from the sexual focus itself. Krafft-Ebing records various cases of masochism in which the emission of urine on to the body or into the mouth formed the climax of sexual gratification, as, for instance (_Psychopathia Sexualis_, English translation, p. 183) in the case of a Russian official who as a boy had fancies of being bound between the thighs of a woman, compelled to sleep beneath her nates and to drink her urine, and in later life experienced the greatest excitement when practicing the last part of this early imagination. In another case, recorded by Krafft-Ebing and by him termed "ideal masochism" (_Op. cit._, pp. 127-130), the subject from childhood indulged in voluptuous day-dreams in which he was the slave of a beautiful mistress who would compel him to obey all her caprices, stand over him with one foot on his breast, sit on his face and body, make him wait on her in her bath, or when she urinated, and sometimes insist on doing this on his face; though a highly intellectual man, he was always too timid to attempt to carry any of his ideas into execution; he had been troubled by nocturnal enuresis up to the age of 20. Neri, again (_Archivio delle Psicopatie Sessuali_, vol. i, fasc. 7 and 8, 1896), records the case of an Italian masochist who experienced the greatest pleasure when both urination and defecation were practiced in this manner by the woman he was attached to.
