Courtship resembles very closely, indeed, a drama or game; and the aggressiveness of the male, the coyness of the female, are alike unconsciously assumed in order to bring about in the most effectual manner the ultimate union of the sexes. The seeming reluctance of the female is not intended to inhibit sexual activity either in the male or in herself, but to increase it in both. The passivity of the female, therefore, is not a real, but only an apparent, passivity, and this holds true of our own species as much as of the lower animals. "Women are like delicately adjusted alembics," said a seventeenth-century author. "No fire can be seen outside, but if you look underneath the alembic, if you place your hand on the hearts of women, in both places you will find a great furnace."[170] Or, as Marro has finely put it, the passivity of women in love is the passivity of the magnet, which in its apparent immobility is drawing the iron toward it. An intense energy lies behind such passivity, an absorbed preoccupation in the end to be attained. Tarde, when exercising magistrate's functions, once had to inquire into a case in which a young man was accused of murder. In questioning a girl of 18, a shepherdess, who appeared before him as a witness, she told him that on the morning following the crime she had seen the footmarks of the accused up to a certain point. He asked how she recognized them, and she replied, ingenuously but with assurance, that she could recognize the footprints of every young man in the neighborhood, even in a plowed field.[171] No better illustration could be given of the real significance of the sexual passivity of women, even at its most negative point. "The women I have known," a correspondent writes, "do not express their sensations and feelings as much as I do. Nor have I found women usually anxious to practise 'luxuries.' They seldom care to practice _fellatio_; I have only known one woman who offered to do _fellatio_ because she liked it. Nor do they generally care to masturbate a man; that is, they do not care greatly to enjoy the contemplation of the other person's excitement. (To me, to see the woman excited means almost more than my own pleasure.) They usually resist _cunnilinctus_, although they enjoy it. They do not seem to care to touch or look at a man's parts so much as he does at theirs. And they seem to dislike the tongue-kiss unless they feel very sexual or really love a man." My correspondent admits that his relationships have been numerous and facile, while his erotic demands tend also to deviate from the normal path. Under such circumstances, which not uncommonly occur, the woman's passions fail to be deeply stirred, and she retains her normal attitude of relative passivity.
