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.

Into this unhappy country, comes the birth control pill, in the 1970s. Now, as long as a pill was taken once a day, the s. Act itself became carefree: no pregnancy! Thete was no STD protection, but this was unimportant because

STDs were eliminated

In the 1950s and 2960s, the only sexually transmitted diseases (as they called them at the time) were syphilis and gonorrhea. Sex ed. materials of the time often presented them as scary figures, out to get the unchaste. Then -- penicillen became generally available. Syphilis was conquered, gonorrhea was controled.No one but doctors had heard of herpes.

The reasons there were so few STDd is that there was so little S. Sex. A low rate if STDs means not much fucking was taking place. (Other types of sex existed, but they were a real fringe. The idea that cocksucking or pussy eating (daintily cslled "fellatio" and "cunnilingus") might merit serious attention from scholars, and be taught, was inconceivable at the time.)

Low STDs and low intercourse went together. If you don't have sex, you can't transmit a sexually transmitted disease. When STDs go up, that means there's been more fucking. (Fucking and intercourse (penis-vagina sex) were ususlly equated )

Pornography became legal

From the beginning, although the word never appeared in the document, it has been taken for granted that obscenity was not protected by the freedom of the press

Video 8 mm vhs, dvd, internet

Phones became cameras

And system (Internet) capacity enabled massive transmission of videos.
