The pornography or obscene material around when I was a kid (all I ever saw was a few issues of Playboy) is nothing compared to either the content or the omnipresence of porn today.
The situations cannot be compared.
I don't know how old you are but there was hard core porn with all the nasty stuff in even 30 and 40 years ago, even longer. Then there were the dirty books I ran across in the bathroom my dad inadvertantly left out...
