The hypothesis that the morning erections are due to a full bladder will be discussed more fully in my work on _Male Impotence_. I do not believe that erection is due to reflex action from the bladder.[34] _But it is an incontestable fact that the dream operates until the existing psychic inhibitions are overcome._ _Hirschfeld’s_ patient is able to have sexual intercourse with his wife only mornings, because through the day and evenings he is under the domination of inhibitions which make him impotent with women. * * * * * That the impotence in such cases does not always denote weakness is illustrated by the following case: C. H., a homosexual physician, tells me that he abstains from touching all drinks because he fears he might commit criminal acts. He is homosexual since childhood and had never felt any inclination towards women. Masturbation began at 9 years of age. It began when his uncle once lifted him upon the shoulder. That gave him a strong pleasurable feeling and soon after that he began rubbing his genitals and while doing so he always fancied that his uncle or some other man was carrying him. He had never felt any desire to be carried similarly by a woman. Such a thing would strike him as degrading and vulgar. His experience in houses of prostitution, from 19 to 24 years of age, filled him with disgust for all women who can be hired. Perhaps he might have been able to have intercourse with a girl of better class but a certain timidity prevented him from ever approaching such a girl. Emancipated women fill him with horror. He maintained relations with a certain colleague for some time. _Coitus inter femora._ At 28 years of age, after a carousal, he met a girl whom he took to a hotel. Powerful erection and prompt coitus. _But with the onset of the orgasm he felt an overwhelming inclination to strangle the girl._ Suddenly a tremendous hatred mounted in his soul against the poor creature. He hurried away from the scene as rapidly as possible. He thought he wanted to revenge himself because through the act of coitus she degraded him. * * * * * Here we see a sadistic attitude towards woman under the cover of timidity. He really feared himself, his criminal tendencies. Problems rising out of the struggle between the sexes (specifically, out of man’s instinctive sex hatred of woman) play a certain role in this case. The significance of this attitude will be explained fully later. This case shows the outbreak of a heterosexual-sadistic instinct under the influence of alcoholic drink. Alcohol seems to dissolve here the defences raised by consciousness against the sadistic tendencies. Very interesting is the case reported by _Moll_ in his work on _The Contrary Sexual Feeling_ (3rd edition). I give here the case in brief extracts from its history, as it contains points of significance in connection with our present subject:
