"In 1961, when the pill was introduced to Britain, women pushed their, often reluctant, doctors to give them the drug. By the late 1960s, young women were talking about a revolution in women’s sexual attitudes, but since then the suggestion that the pill just meant women couldn’t say no has been widely repeated, alongside negative assessments of the ‘sexual revolution’. As early as the 1880s, there had been suggestions that fear of pregnancy gave wives an excuse for denying their husbands their conjugal right of sexual intercourse. By the early 1990s, over 80 per cent of British women of reproductive age since the early 1960s had taken the pill."
