While the totally anaesthetic woman has no natural desire for coition, and in this respect resembles the woman who is suffering from idiopathic frigidity or impotence of voluptas, the woman with the power of experiencing libido, but afflicted with the anomaly of orgasmus retardatus, has an intense desire for conjugation. She seeks it oftener than the normal woman, for the reason that her desire is seldom satisfied. She demands, therefore, commixtionem continuam per horas et pæne quot noctibus. Such a Messalina is able commisceri centies in una nocte and yet be unsatisfied. Even if she had it in her power, like Katherine of Russia, to order cubili suo a whole regiment of soldiers quot noctibus, she would still remain unsatisfied. This anomaly, for these reasons, may often be confounded with the perversion of nymphomania, where a normal orgasm is induced with every copulation, but where an immediate reawakening of desires, after normal satisfaction, takes place. Through the similarity of the symptoms of orgasmus retardatus and nymphomania great mistakes in treatment have often been committed. The wisdom of amputating the clitoris in a case of nymphomania is very questionable, but the advice to amputate it in a case of impossible or retarded orgasm and permanently damage the already weakened nerves is a mistake that borders almost to malpractice. For the amputation of the clitoris will impede the inducement of the orgasm even to a greater extent than before. The genital apparatus, which was weakened by excesses in venere or in narcotics, is now irreparably destroyed for all time. The case of Barrus shows what clitoridectomy may sometimes do. The patient, a young woman, stuprum faciebat manu more or less, all her life, and finally after suffering from several attacks of nymphomania decided to have the clitoris amputated. The result was not only failure to relieve the alleged nymphomania, but even an increase in its severity, causing a shameless and, almost literally, continuous indulgence in the habit. The cause of orgasmus retardatus is almost always self-abuse, either in form of masturbation, mental erethism, or tactile eroticism. The excitability of the clitoris is so increased through these practices that it refuses to transfer its excitability upon the internal genital organs for the inducement of orgasm by coition. The ant-orgastic pleasure is hence intact or even increased, but the orgasm is seldom or never provoked.
