Nostalgia may not be what it used to be, but you did used to be able to have casual sex... with no repercussions assuming appropriate barriers... and it wasn't a big deal, it was just sex for crying out loud. I miss the 70's! Nowadays everybody's so tied up in what it MEANS - how 'bout it means let's enjoy some sex, and if not, no biggie? (I did not grow up in the US of A, which I think had a lot to do with it.)
