youkiddingme I would love an answer to that question.
I suspect the answer is "yes" they've always been obsessed with sex - but that the obsession was kept under wraps more.
The total availability with online porn has shifted something in society.
I grew up in the 70s - when porn was magazines of vhs videotapes. There was a reputation of them being "under the counter" and "top shelf" and "carried in brown paper bags" by men wearing macs.
I remember schoolboys crowding around a boy who had maybe managed to nick one his dad's porno mags, and brought it into school.
I remember my friend showing me her dad's stash of magazines in the bathroom cupboard.
Things are so, so different now. It is not something men need to feel they have hide away now - we're not allowed to "kink shame" now for some reason - and similarly, I don't think men are remotely ashamed of watching porn either. And porn constantly pushes the boundaries - more explicit, more extreme - I agree it's a complete shift of the overton window.
