ELI5: Explain Like I'm 5

Sexual revolution

The sexual revolution happened in the 1960s and 1970s. It was a time when people started talking about sex more openly and not keeping it hidden. They did things that were new and different, like having sex with more than one partner. They also talked more openly about birth control and sexual orientations, which are the things that make someone attracted to certain kinds of people. All of this changed the way people saw sex and made it easier for people to talk about and do whatever they were comfortable with.
