In the majority of cases the sexual frigidity of woman is, in fact, apparent merely--either because behind the veil prescribed by conventional morality, behind the apparent coldness, there is concealed an ardent sexuality, or else because the particular man with whom she has had intercourse has not succeeded rightly in awakening her erotic sensibility, so complicated and so difficult to arouse.[32] When he has succeeded in doing so, the sexual insensibility will in the majority of cases disappear. A striking example of this is seen in the following case: =Case of Temporary Sexual Anæsthesia.=--Girl twenty years of age. Early awakening of the sexual impulses. Already practised onanism at the age of five years; often for the sake of sexual stimulation introduced hairpins into the vagina, until one day one of these remained, and had to be removed by operation. Notwithstanding this, she soon resumed masturbation, using for this purpose a finger, a candle, etc. Ultimately this became a daily practice, which she continued until she was eighteen years of age. She then first had sexual intercourse with a man, in which, however, she remained quite cold; this was the case also in subsequent attempts with this man and with others. Finally she met a man with whom she was in sympathy, who succeeded in inducing in her sexual gratification, by exchange of rôles, and corresponding alteration in the position in intercourse. Later, intercourse in the normal position also induced complete sexual gratification; since then onanism has been entirely discontinued, and in coitus the orgasm occurs speedily in one or two minutes. Where sexual frigidity in woman is enduring in character, we have to do either with inherited influences, with sexual developmental inhibition, the psycho-sexual infantilism of Eulenburg, or with some disease (especially hysteria and other nervous disorders), and with the consequences of habitual masturbation. Speaking generally, the sexual sensibility of woman is, as we have seen, of quite a different nature from that of man; but in intensity it is at least as great as that of man.
