I. E. Colla has reported on “Three instances of homosexual deeds during drunkenness,” in the Vierteljahrschrift für gerichtliche Medizin und öffentliches Sanitätswesen,[29] as follows:

The first case was a 29 year old inebriate who had had a wide experience with women and carousals; after a prolonged period of abstinence he became intoxicated while in a sanitarium, was seduced by a homosexual, and immediately after that, while in an intoxicated state, he attempted to attack a servant. Repetition of similar episodes when under the influence of drink but when sober exclusive breaking forth of heterosexual feelings. A clear proof in favor of my view about the relations of latent homosexuality to satyriasis.

In the second case a controlled homosexual leaning breaks forth overpowering the subject when drunk. A similar picture in the third case: A protestant minister, 37 years of age, drinker, loses his self-control while drunk and by his offensive behavior in a public place attracts the attention of the authorities.

Numa Praetorius, that thorough expert on homosexuality, relates: “In many cases homosexual deeds are committed under the influence of alcohol. Thus, for instance, I know a former police officer, a homosexual, who when drunk attempts homosexual deeds upon heterosexual comrades, who excite him, although he is acquainted with the homosexual circle, is intimate with many homosexuals, and in his sober state he carries out relations only with persons with whom he is safe. On account of these attacks on heterosexual persons during his drunken condition he has lost his position as police officer as well as his later position in a factory.

“Another homosexual, a merchant, thirty years of age, when drunk finds this inclination uncontrollable and has tackled the wrong persons while in that state. There is a great deal of truth in the contention that during the inebriate state man’s true character comes to surface,—at any rate his true sexual character certainly reveals itself in that state, since the customary inhibitions are curtailed. Here ‘in vino veritas’ certainly holds true.” (Jahrbuch f. Sexuelle Zwischenstufen, Vol. VIII.)

These cases, with the exception of the first, show only an increase of an already existing homosexual inclination otherwise under control. But frequently it happens that heterosexual persons carry out their first homosexual aggression during the inebriate state.

Thus Praetorius remarks in another passage: “As is disclosed in various published biographies as well as in certain communications which have reached me orally, there are young persons, otherwise apparently normal in feeling and conduct, who when drunk are attracted to their own sex with a great feeling of pleasure thus disclosing more than a pseudo-homosexual attitude. But their proper heterosexual nature does not appear to be changed materially by these occasional homosexual episodes and emotional sprees.”

Hugo Deutsch[30] has reported a very instructive case, which, although far from unique, as the author believes, may be mentioned in this connection:

“An intelligent workingman, 39 years of age, appeals for advice and information to the clinic for alcoholics. As a child he suffered of rachitis and began walking only at four years of age; excessive masturbation as a small boy and young man; later, occasional intercourse with girls; he married two years ago and is the father of two children. No illness, with the exception of minor complaints. Uses alcohol moderately, drinks now and then one-half to one litre of beer on the occasion of some reunion or meeting. But this always excites his sexual passion; specifically he feels impelled to take advantage of young male persons[31] so as to touch and feel their sexual parts. He has been able to withstand this desire but once while on his way home from a meeting where he had again taken a couple of glasses of beer he met a young boy whom he invited to have a drink with him and while they were sitting at a table in the saloon he touched the boy’s genitals. A customer saw this and denounced him to an officer who arrested him. He was in despair over the occurrence and only the thought of his wife and children prevented him from committing suicide. He has not touched a drop of alcoholic drink since because he recognizes how dangerous even a small amount of drink may be for him. So long as he is sober his libido is directed exclusively to women, in fact he feels only disgust and aversion for any homosexual deeds. When the contrary feeling first arose in connection with drink he cannot recall. There is nothing relevant in this connection in his family history and there is nothing “womanly” in his physical appearance.”

Deutsch believes that this is a case of bisexuality brought to surface because the use of even moderate doses of alcohol suspends the existing inhibitions.
