Couple of illustrations:

Macro - CDC: 40% of all births are to unmarried parents (in the US)

Micro - Article titled "Miley Cyrus and Kaitlyn Carter were 'basically having sex in a club'"

These are new things. Very few births used to be to unmarried parents, for example, and there was a time when such an article simply would not have been published (and maybe even such an event unlikely to occur in public? I dunno)

So are the changes in sexual norms, whatever you perceive them to be, better, or worse, however you define that?

And what kind of further changes to the norms would you prefer, in either direction?
