In the last case the heterosexual act was possible only after neutralizing the inhibitions. Similar influences are responsible for the well-known morning erections of those who are psychically impotent. Homosexuals, too, have heterosexual dreams before awakening in the morning but they cannot—or will not—remember those dreams. I need mention here merely that every night the dream operates in the sense of lifting the inhibitions and that the inhibitions are fully suspended only towards morning. During the first sleep hours the dreams are full of inhibitions appearing as “warnings,” but towards morning the dreams are relatively free of these inhibitions. That is why we often hear that “genuine” homosexuals are able to have intercourse with women, if at all, only towards morning. At that time most inhibitions which stand between them and woman have been overcome in the dream! This obvious fact is given a different interpretation by _Hirschfeld_ who states: “The erection of the _membrum_ with which many men wake up during the early morning hours has nothing to do with the sexual instinct, but is due solely to the mechanical effect of pressure by the full bladder. Some time ago I was consulted by a homosexual, married, father of six children and expecting the arrival of a seventh. I asked him how that was possible. ‘That is very simple,’ he answered, not without a certain feeling of self-consciousness, ‘I always took advantage of my morning erections.’ Thus the children owe their existence not to the father’s sexual instinct, but to the operation of his full bladder. The much-praised aphrodisiacs, are probably also nothing more than diuretics; in other words it may well be that the renown which certain remedies and articles of diet have acquired as stimulants of the _potentia coeundi_ may well be due to their stimulating effect upon the bladder function and its genital reflex. “Alcoholic drinks, when taken in small quantities have a similar effect and rouse the sexual function. Excesses _in Baccho_ and venereal excesses have always been looked upon as belonging together. This is so because alcohol has the effect of lowering the inhibitions and at the same time it appears to weaken the mental acuity. We may thus see why occasionally heterosexuals confess that they have taken up with some man under the influence of drink, and homosexuals that, _when intoxicated_, they can have intercourse with women.” (_Hirschfeld_, l.c., p. 189.) But the fact that homosexuals are capable of heterosexual activity under the influence of drink is for me a proof of their bisexuality, a proof that that they have repressed the heterosexual component of their sexual instinct.
