It seems to me probable that such hermaphrodites from constitutional taint are not infrequent.[113] Since they attract very little attention socially, and since such secrets of married life are only exceptionally brought to the knowledge of the physician, it is at once apparent why this interesting and practically important transitional group to the group of absolute contrary sexuality, has thus far escaped scientific investigation. Many cases of frigiditas uxoris and mariti may possibly depend upon this anomaly. Sexual intercourse with the opposite sex is, in itself, possible. At any rate, in cases of this degree, no horror sexus alterius exists. Here is a fertile field for the application of medical and moral therapeutics (_v. infra_). The differential diagnosis from acquired contrary sexual instinct may present difficulties; for in such cases, as long as the vestiges of a normal sexual instinct are not absolutely lost, the actual symptoms are the same (_v. infra_). In the first degree, the sexual satisfaction of homo-sexual impulses consists in passive and mutual onanism and coitus inter femora. Case 106. _Psychical Hermaphroditism in a Lady._—Mrs. M., aged 44, exemplifies the fact that an inverted and a normal sexual instinct may be united in one person, be it in man or woman. The father of this lady was very musical, and very talented as an artist. He took life easily; and to his extraordinary beauty was added a great admiration for the opposite sex. After several apoplectic attacks, he died demented in an asylum. Father’s brother was neuro-psychopathic, and when a child was a somnambulist; and all his life he was afflicted with hyperæsthesia sexualis. Thus, although married and the father of married sons, he tried to seduce his niece, Mrs. M., with whom he was wildly in love, when she was eighteen years old. Father’s father was very eccentric and a distinguished actor. He first studied theology, but, as a result of partiality for the dramatic muse, he became an actor and singer. He committed excesses in baccho et venere; was a spendthrift and luxurious. He died at forty-nine, of apoplexia cerebri. Mother’s father and mother died of tuberculosis of the lungs. Mrs. M. was one of eleven children, of whom six are still living. Two brothers, who resembled the mother physically, died, at sixteen and twenty, of tuberculosis. A brother suffers with laryngeal phthisis. Four living sisters and Mrs. M. resemble the father physically, and the eldest is unmarried, very nervous, and shy of people. Two younger sisters are married, healthy, and have healthy children. The other is unmarried, and suffers with nervous complaints. Mrs. M. has four children, several of whom are delicate and neuropathic.
