The eras are completely different as regards price, choice, volume, and ease of viewing.
We are living in an era where porn has never been so easily available in such volume to so many. Free, whatever, whenever on whatever device you want to watch it on.

The question is one of when you have burned through all your 'kicks' by 20, what are you going to do for a thrill? How are you going to settle down to a monogamous relationship?
When does glorifying female form (for guys, male for women) give way to acting out porn induced fantasies, and where does that go off the rails and become really sick or even deadly?
I don't believe that is the road The Almighty wanted us to take.
