Forget the 1960s. The biggest changes in sexual mores came between 1600-1800, when more sexual freedom - albeit mainly for men - and a belief that sexual activity was largely a private, not a public matter, laid the foundations for much contemporary Western thinking on sex. This is the argument made by Oxford University historian Faramerz Dabhoiwala, in his acclaimed book.
