I think we were more impressionable back in the day because we were younger, too.
There are 15-16 yo boys sneaking peeks at their pop's "Anal Princess Diary" dvd's who will be singing Hillary Scott's praises in 15 years. And they'll think Ginger Lynn is as gross as we fans of the "golden age of porn" think Vanessa del Rio was.
There is nothing new under the sun, especially not in pornography.
