Sexual revolution

Sexual revolution is the name for a number of behavioral changes that took place in the second half of the twentieth century, as a result of which the world became more liberal about sex. (Local differences existed in many countries.)

Birth-control pill

The United States, with a puritanical component in it from the beginning (the Puritans), tried to suppress birth control information harder than any other nation in the world as of that time. It became illegal in the latter bibeteenth century to send birth control information.through the mail (or sex toys either, which in 2017 remain illegal in Alabama). The pessary, used casually in pre-World War II France by Anaïs Nin, was unknown. Condoms, if available at all, were "for the prevention of disease only"; they were never on open shelves as they are in the modern (2017) supermarket, but were behind the counter in phamacies and had to be asked for. The idea that sex might be fun, though often admitted in private, was all but anathema to the establishment of the time.
