Although the organic phenomenon of the accumulation of semen in the seminal vesicles is absent in woman, there is produced in the nerve centers, after prolonged abstinence, an accumulation of sexual desire corresponding to that of man. A married woman confessed to me, when I reproached her for being unfaithful to her husband, that she desired coitus at least once a fortnight, and that when her husband was not there, she took the first comer. No doubt the sentiments of this woman were hardly feminine, but her sexual appetite was relatively normal. =Frequency of the Sexual Appetite in Woman.=--As regards pure sexual appetite, extremes are much more common and more considerable in woman than in man. In her this appetite is developed much less often spontaneously than in him, and where it is so, it is generally later. Voluptuous sensations are usually only awakened by coitus. In a considerable number of women the sexual appetite is completely absent. For these, coitus is a disagreeable, often disgusting, or at any rate an indifferent act. What is more singular, at least for masculine comprehension, and what gives rise to the most frequent "quid pro quos," is the fact that such women, absolutely cold as regards sexual sensations, are often great coquettes, over-exciting the sexual appetites of man, and have often a great desire for love and caresses. This is more easy to understand if we reflect that the unsatiated desires of the normal woman are less inclined toward coitus than toward the assemblage of consequences of this act, which are so important for her whole life. When the sight of a certain man awakes in a young girl sympathetic desires and transports, she aspires to procreate children with this man only, to give herself to him as a slave, to receive his caresses, to be loved by him only, that he may become both the support and master of her whole life. It is a question of general sentiments of indefinite nature, of a powerful desire to become a mother and enjoy domestic comfort, to realize a poetic and chivalrous ideal in man, to gratify a general sensual need distributed over the whole body and in no way concentrated in the sexual organs or in the desire for coitus.
