Has it? Really? I'm pretty sure culture in the US has become significantly more overtly erotic over the past 30 years...

Depends on what you mean - in a very overt, marketed and non-french way, sure.

Yes, and no. in my eyes we compartmentalized sexuality to its own "dark" pocket of the internet. But in that corner it's more diverse, extreme, and widespread as ever.

The latest waves of trying to ban porn certainly shows that this isn't what those in power desire, though.
