[30] _Alkohol und Homosexualität. Wiener klinische Wochenschrift_, 1913, No. 3. [31] Krafft-Ebing also mentions a young man who carried out his first homosexual aggression under the influence of alcohol. A man who previous to that time had successful intercourse with prostitutes while intoxicated grabbed hold of his friend’s genitals, they masturbated ... and since that time he is homosexual. [32] _Zur Psychologie des Alkoholismus_, _Zentralbl. f. Psychoanalyse u. Psychotherapie_, vol. III, p. 1. [33] Interesting is also the case of a high school teacher whose feelings were predominantly homosexual during the stage of depression and heterosexual during the stage of exaltation induced by the addiction to morphine (_Hirschfeld_). There are persons who live a double, alternating existence: homosexual and heterosexual. Their conduct suggests that they are persons continually in search of a bisexual ideal. Krafft-Ebing also describes a hysterical (_Jahrbuch f. Sexuelle Zwischenstufen_, vol. III) who is attracted to men each time that her neurosis improves after a sojourn at a sanitarium, while during the height of her trouble she is homosexual. What does this mean but that the heterosexual cravings are repressed during her neurosis! For notwithstanding her extensive homosexual gratifications she has become a victim of severe hysteria while every time she improves she feels the love for man. [34] Cf. author’s contribution, _Die psychische Impotenz des Mannes_. Zeitschr. f. Sexualwissenschaft, 1916. [35] _Beiträge zur Lehre von der konträren Sexualempfindung_, Zeitschr. f. Psychol, u. Neurol., vol. VII, 1911. [36] _Alkohol und Homosexualität._ Allg. Zeitschr. f. Psychol. und gerichtl. Medizin, vol. LXVIII. [37] It is not true that homosexuals are exposed to no dangers of infection. I have examined a homosexual druggist who acquired in Venice a serious gonorrhea of the anus. He confessed to me that he had infected other men, because the thought of having fallen himself a victim made him angry. But on the whole infections are not so frequent an occurrence as during heterosexual intercourse, which is what would be expected, considering that _copulatio analis_ is relatively rare.
