ATTITUDE TOWARD THE OPPOSITE SEX.
In 17 cases (of whom 5 are married and others purposing to marry) there is sexual attraction to both sexes, a condition formerly called psychosexual hermaphroditism, but now more usually bisexuality. In such cases, although there is pleasure and satisfaction in relationships with both sexes, there is usually a greater degree of satisfaction in connection with one sex. Most of the bisexual prefer their own sex. It is curiously rare to find a person, whether man or woman, who by choice exercises relations with both sexes and prefers the opposite sex. This would seem to indicate that the bisexual may really be inverts.
In any case bisexuality merges imperceptibly into simple inversion.
In at least 16 of 52 cases of simple inversion in men there has been connection
with women, in some instances only once or twice, in others during several
years, but it was always with an effort, or from a sense of duty and anxiety
to be normal; they never experienced any real pleasure in the act, or sense
of satisfaction after it. Four of these cases are married, but martial
[sic] relationships usually ceased after a few years. At least four
others were attracted to women when younger, but are not now; another once
felt sexually attracted to a boyish woman, but never made any attempt to
obtain any relationships with her; 3 or 4 others, again, have tried to
have connection with women, but failed. The largest proportion of my cases
have never had any sexual intimacy with the opposite sex, and some of
these experience what, in the case of the male ...
 Hirschfeld also finds, among German inverts (Die Homosexualitaet, ch. iii), that the majority (though a smaller majority than I find in England and the United States) have not had intercourse with women; 53 per cent., he states, including a few married men, have never even attempted coitus, and over 50 per cent. are presumably impotent. The number of inverted women who have never had intercourse with men is still larger.
... invert, is sometimes called horror feminae. But, while woman as an object of sexual desire is in such cases disgusting to them, and it is usually difficult for a genuine invert to have connection with a woman except by setting up images of his own sex, for the most part inverts are capable of genuine friendships, irrespective of sex.
It is, perhaps, not difficult to account for the horror - much stronger
than that normally felt toward a person of the same sex - with which the
invert often regards the sexual organs of persons of the opposite sex.
It cannot be said that the sexual organs of either sex under the influence
of sexual excitement are esthetically pleasing; they only become emotionally
desirable through the parallel excitement of the beholder. When the absence
of parallel excitement is accompanied in the beholder by the sense of unfamiliarity
as in childhood, or by a neurotic hypersensitiveness, the conditions are
present for the production of intense horror feminae or horror
masculis, as the case may be. It is possible that, as Otto Rank argues
in his interesting study, "Die Naktheit im Sage und Dichtung," [sic]
this horror of the sexual organs of the opposite sex, to some extent felt
even by normal people, is embodied in the Melusine type of legend.
