Among masturbating females sixty per cent, according to Kinsey, indulge in heterosexual fantasy. This is hardly surprising since most females are heterosexual; only ten per cent of women had homosexual fantasies while masturbating.

Our woman sadist, unlike de Sade, was a practising person, i.e. she wrote no books but killed and tortured to her heart's content. In 1611, aged fifty, the Hungarian noblewoman Erzsebet Bathory was walled up alive in her castle in the Minor Carpathians for having killed some six hundred young girls in various ways. The judge at her trial appears to have been particularly concerned that she murdered noblewomen as well as mere servant-girls. Bathory used a number of ingenious devices. For instance, she put a terrified naked girl in a narrow iron cage

Solon, the law-giver, introduced the first publicly administered brothel in the Athens of 550 B.C. The brothel, soon copied in nearby cities, was run by slaves; and the inmates were also slaves. the lowest class of Greek prostitute. From the taxes collected from the licensed brothels (Dicteria), Solon built a temple to the Goddess Aphrodite. There is a passage in Athenaeus to show the gratitude of the citizens for Solon's wisdom in establishing a brothel which would give an outlet to lustful impulse without endangering the social order-

Incest, evoking a variety of taboo responses, is condemned equally in primitive and advanced societies. International incidences have been reported as high as five per million population per year, and isolated pockets within a nation have been even higher, i.e. seven per million in the State of Washington. New Zealand has the record with a figure of nine per million population per year.

Every imaginable type of human being has been required for purposes of prostitution. In Italy a ring of grand-mother prostitutes was uncovered by the police.

Amputees have also been immensely popular. Not so long ago a woman with one leg was operating in the San Francisco area: "she claimed to have more business than she could handle." Hunchbacks and women with one or both breasts amputated have also been immensely popular. Similarly some men apparently desire a woman with a club foot or females with hideous scars.

By the eleventh century the Franciscans were extolling self-flagellation as a penance. And the Italian Benedictine St. Pietro Damian organised group flagellation for laymen. Two hundred years later a procession of fanatical flagellants - closely linked to the Flagellant sect - set out under the auspices of St. Anthony of Padua. This austere saint, theologian and preacher-keen to combat manifest sexuality - was in fact adding to the sexual ferment. In 1260 unofficial processions of voluntary scourgers, each member heartily whipping the man in front of him,

One of the curious things about sexual behaviour is that it correlates - in frequency, variety, etc. - with social class.

Kinsey found that masturbation was more common in educated classes than in those groups concerned with unskilled or manual labour. Of all classes the professional groups masturbate most.

This is almost certainly Christine Keeler, born in 1942, the British call-girl at the centre of the "Profumo Affair" scandal of 1963. She left home at 16, met Stephen Ward, and later became involved in a wide range of sexual activities in the Ward circle - nude parties, group sex, flagellation, voyeurism, etc. Christine met John Profumo, then Secretary of State for War, at Cliveden: he was attracted to her after seeing her swimming nude in the pool of Lord Astor. After a security warning Profumo stopped seeing Christine, but later lied about the affair to the

Court brothels existed during the time of Charlemagne and later a well-equipped brothel was established by contemporaries of George III. This latter establishment comprised a group of houses near St. James's Palace, in a lane called "King's Place": the employed girls were only allowed to walk in the royal parks, and only the innermost circle of the court was allowed to frequent the court brothel.

Chinese lovers - in pre-Mao days - were said to be fond of fowl. Mantegazza has remarked that "The Chinese are famous for their love affairs with geese ..." This would be remarkable enough: the actual way the Orientals used such a creature for sexual purposes is even more extraordinary. At the moment of ejaculation the man would pull the head off the live animal to get "the pleasurable benefit of the anal sphincter's last spasms in the victim."
