In the woman an analogous phenomenon takes place; the clitoris becomes turgid and the mild and repeated friction of the mucous membranes, together with contact on other sensitive parts, produces a voluptuous sensation as in the man. Through nervous association, the repeated excitation determines secretion from certain glands of the vagina which lubricate the vulva (glands of _Bartholin_). At the maximum point of voluptuous feeling the woman experiences something analogous to the venereal orgasm of the man. There is thus manifested in the two sexes an intense and reciprocal desire of penetration one by the other, a desire which powerfully favors fecundation. In the woman as in the man the end of the orgasm is followed by an agreeable relaxation which invites sleep. The hereditary or instinctive nervous actions produce after coitus a profound effect of contrast. When the sexual appetite commences, the odors, especially those of the sexual organs, the contacts, the movements, and the sight of the individual of the opposite sex, all increase desire, producing a voluptuous excitation stronger than all contrary feeling. Hardly is the sexual act consummated than all vanishes like a dream. What was a moment before the object of the most violent desire becomes indifferent, and sometimes even excites a slight feeling of disgust, at least as regards certain odors, sometimes even regarding touch and sight. The name sexual appetite (libido sexualis) is given to the passionate and purely sexual desire of the two sexes for each other. It varies greatly in different individuals.
