In 1558 an anatomist called Columbus discovered the clitoris, and so a whole new world of sexual pleasure began to be opened up - and it was a steady progress that culminated in the present Golden Age. That at least is the official history. Here Jonathan Margolis produces evidence to show that in Europe and America progress was extremely slow whilst in other places the secrets of the orgasm created almost unimaginable worlds of pleasure. The book will draw on orgasm's biology, anthropology, psychology, technology and sociology. The orgasm was revered in ancient societies, but by the 13th Century modesty ruled: St Francis of Assisi would throw himself into a thorn bush to disguise unwanted erections and avoid all possibility of orgasm. Victorians still regarded the female orgasm as a form of hysteria - women were treated for hysteria and, by the 19th century, were strongly advised against riding bicycles for this reason. In Edwardian Britain and America, vibrators were routinely advertised in the respectable women's magazines as a form of handy household appliance. Margolis considers the revival of open, public interest in sex in the late 1950s, and the effect of the Pill, feminism and Viagra on the state of the orgasm in the 21st century.
