R.D., aged 25, married, and of good social position; she is a
    small and dark woman, restless and alert in manner.  She has one
    child.

She has practised masturbation from an early age—­ever since she can remember—­by the method of external friction and pressure.  From the age of 17 she was able (and is still) to produce the orgasm almost without effort, by calling up the image of any man who had struck her fancy.  She has often done so while seated talking to such a man, even when he is almost a stranger; in doing it, she says, a tightening of the muscles of the thighs and the slightest movement are sufficient.  Ugly men (if not deformed), as well as men with the reputation of being roues, greatly excite her sexually, more especially if of good social position, though this is not essential.

At the age of 18 she became hysterical, probably, she herself believes, in consequence of a great increase at that time of indulgence in masturbation.  The doctors, apparently suspecting her habits, urged her parents to get her married early.  She married, at the age of 20, a man about twice her own age.

As a child (and in a less degree still) she was very fond of watching dog-fights.  This spectacle produced strong sexual feelings and usually orgasm, especially if much blood was shed during the fight.  Clean cuts and wounds greatly attract her, whether on herself or a man.  She has frequently slightly cut or scratched herself “to see the blood,” and likes to suck the wound, thinking the taste “delicious.”  This produces strong sexual feelings and often orgasm, especially if at the time she thinks of some attractive man and imagines that she is sucking his blood.  The sight of injury to a woman only very slightly affects her, and that, she thinks, only because of an involuntary association of ideas.  Nor has the sight of suffering in illness any exciting effects, only that which is due to violence, and when there is a visible cause for the suffering, such as cuts and wounds. (Bruises, from the absence of blood, have only a slight effect.) The excitement is intensified if she imagines that she has herself inflicted the injury.  She likes to imagine that the man wished to rape her, and that she fought him in order to make him more greatly value her favor, so wounding him.

Impersonal ideas of torture also excite her.  She thinks Fox’s Book of Martyrs “lovely,” and the more horrible and bloody the tortures described the greater is the sexual excitement produced.  The book excites her from the point of view of the torturer, not that of the victim.  She has frequently masturbated while reading it.

So far as practicable she has sought to carry out these ideas in her relations with her husband.  She has several times bitten him till the blood came and sucked the bite during coitus.  She likes to bite him enough to make
