I hear what you are saying man. One thing that has always blown my mind is the sheer number of these girls. Hot, young(often teen), normal looking girls with great bodies getting their asses blown out and getting their faces painted with man gravy. Millions of them. What the fuck? Like you said, where is this non-stop supply of girls coming from? Back in the day it was rare to see porn chicks that weren't kinda ugly and skanky. They were polished turds that wore a tone of makeup and got fake tits to look hotter than they really were. Shit done changed. Now there are some legit 9's in porn having all types of nasty shit done to them with a smile. I'm terrified to have a daughter in this society.
Full disclosure. Although I find porn morally wrong and a big part of the downfall of our society, I still watch it all the time. In my mind it's pretty much the best (and worst) thing in the history of the world.
Take a look at home life. Many may start out as strippers, escorts, some get recruited (look at Brian Pumper's show on YouTube). Then you have the women who are curious, and those who just don't give a damn. In today's world, porn is not as taboo. So, a woman who is in a dead end job, or in college and is thinking about paying tuition, but not thinking about how this decision may affect her future (mentally, physically, and career wise), is more willing to do this.
You'd be surprised at the sheer number of women who escort. It's almost like we as a society through the advocacy of debauchery and broken homes have created a never ending supply of women willing to to do porn
or prostitution.
I believe Howard Stern or someone from porn had said "Thank God for women from broken homes..."
And that sums it up in a nutshell. Our society's home life puts more emphasis on having fun, the here and now, than it does on family.
