In all I have had to do with 81 other women, of whose special characteristics I kept a careful note at the time. Twenty-six were normal women with whom my _liasons_ have lasted long, so I know more about them than I do about the other fifty-five, who were prostitutes, and with some of whom my dealings were but for an afternoon. The races represented have been these, for I have seen a bit of the world: English, Scotch, Irish, Welsh, French, German, Italian, Greek, Danish, Hungarian, Roumanian, Indian, and Japanese. Taking them all round, the only difference that I found between old and young women is that the older ones are less selfish, and more complaisant, and less inclined to resent one's being unable to attain to the height of their desire, for from time to time I have been unable to "come up to the scratch" after a heavy night's labor, or when I was afraid of being caught in the act of coition, a fear which, in my experience, acts as a stimulus to desire in women, unlike its action in men. Of all the women with whom I have had to do the nicest in every way have been the French women. The English women of the town drink too much, and are far too keen on getting as much money as they can for as little as they can, to please me. Were the London girls to recognize that men do not like a tipsy woman, and that where there is so much competition the person who is most skillful and most polite gets the most custom, the alien invasion in Regent street would soon come to an end. Of the fifty-five prostitutes: eighteen informed me that they were in the habit of masturbating; eight of their own free will, without asking for reward, did _fellatio_; six asked me to do _cunnilingus_, which I naturally declined to do; three proposed anal coitus. Of those who did _fellatio_, two (one French and one German) told me that they had taken to it because they had heard that human semen was an excellent remedy against consumption, which disease had carried off some of their relatives, and that they had gradually come to like doing it. All who told me that they masturbated, asked me whether I did so too, and two desired me to show them the act, one alleging that she liked to see a man do it; she had been married late in life, after a "stormy youth" and had had, she said, a large experience of the male sex. They all seemed to think that however much the practice of self-excitement might hurt a man, and all thought that it would hurt him, a woman might masturbate as often as she liked, failing better means of satisfaction, as she had no such loss of substance as a man.
