There is a process at work which I am inclined to designate as the fundamental law of sex. According to this law every individual tends to sum up all his instinctive sexual cravings in one image. Every person seeks the sexual ideal capable of satisfying all his sexual longings. The sexual ideal of the ancients was, clearly, a bisexual being. Divinity is the ideal erotic goal magnified. The first divinities were always bisexual. They were either women with a penis or men with a female breast. The longing for the bisexual ideal may be traced throughout humanity. In his Banquet, _Plato_ has excellently expressed this longing in the well-known words of _Aristophanes_. We feel that we are utilizing but a portion of our sexual energy and that the remainder is allowed to remain fallow. The various sexual trends are sometimes so split up in life that no part of them is sufficient alone to furnish the whole driving power for the proper sexual activity. This is the case with those who apparently manifest a diminished sexual craving, as _Freud_ and _Havelock Ellis_ have observed with reference to certain homosexuals. This condition is only apparent, however, and analysis discloses that it is not real. Persons of this type, apparently asexual, really vacillate back and forth between various possible sexual goals never reaching the stage of aggression, because they are incapable of attaining a sufficient summation of sexual libido. Their libido splits up into a number of autoerotic acts, through which the fore-pleasure instead of centering on a focus is expended in small instalments, as I have pointed out when I described the various forms of cryptic onanism. I repeat: the ideal of every person is to be able to concentrate all libido upon a single goal. That explains why the homosexual does not seek the typical male, except in the rarest instances. _Freud_ has drawn our attention to this apparent contrast. Many homosexuals, particularly those who, themselves, possess strong virility, do not seek out the complete male for their ideal, but the womanly male. They prefer the female type of man, men in female clothes, or of female habitus,—a fact which has shaped a great deal the course of male prostitution. The male prostitute endeavors always to imitate the female through the use of trinkets, corset, the adoption of articles of female apparel, close shaving, peculiar gait and speech. What the homosexual seeks consciously the latent homosexual, as we designate the neurotic and, in smaller measure, every individual who acts exclusively as a heterosexual, endeavors to attain through vague yearnings which he fails to understand but which are strong enough to break through.
