Krafft-Ebing himself, in the earlier editions of _Psychopathia Sexualis_, gave little special attention to inversion in women, although he published a few cases. Moll, however, included a valuable chapter on the subject in his _Konträre Sexualempfindung_, narrating numerous cases, and inversion in women also received special attention in the present Study. Hirschfeld, however, in his _Homosexualität_ (1914) is the first authority who has been able to deal with feminine homosexuality as completely co-ordinate with masculine homosexuality. The two manifestations, masculine and feminine, are placed on the same basis and treated together throughout the work. It is, no doubt, not difficult to account for this retardation in the investigation of sexual inversion in women. Notwithstanding the severity with which homosexuality in women has been visited in a few cases, for the most part men seem to have been indifferent toward it; when it has been made a crime or a cause for divorce in men, it has usually been considered as no offense at all in women.[145] Another reason is that it is less easy to detect in women; we are accustomed to a much greater familiarity and intimacy between women than between men, and we are less apt to suspect the existence of any abnormal passion. And, allied with this cause, we have also to bear in mind the extreme ignorance and the extreme reticence of women regarding any abnormal or even normal manifestation of their sexual life. A woman may feel a high degree of sexual attraction for another woman without realizing that her affection is sexual, and when she does realize this, she is nearly always very unwilling to reveal the nature of her intimate experience, even with the adoption of precautions, and although the fact may be present to her that, by helping to reveal the nature of her abnormality, she may be helping to lighten the burden of it on other women. Among the numerous confessions voluntarily sent to Krafft-Ebing there is not one by a woman. There is, again, the further reason that well-marked and fully developed cases of inversion are probably rarer in women, though a slighter degree may be more common; in harmony with the greater affectability of the feminine organism to slight stimuli, and its lesser liability to serious variation.[146] The same aberrations that are found among men are, however, everywhere found among women. Feminine inversion has sometimes been regarded as a vice of modern refined civilization. Yet it was familiar to the Anglo-Saxons, and Theodore's Penitential in the seventh century assigned a penance of three years (considerably less than that assigned to men, or for bestiality) to "a woman fornicating with a woman." Among the women of savages in all parts of the world homosexuality is found, though it is less frequently recorded than among men.[147]
