This question yet again? Seriously now what is so hard to understand about this? Women who decide to have sex for money do it...wait for it...for the money. Didn't we already cover this ground in another thread?
As far as the supposed model SO, there's almost nobody I'd rather not be in this whole world, except maybe a lifeless TUSCL troll. He's probably never going to make much money in this life, so his youth is the only time where he's gonna get his bites of that shiny young ass apple, yet he has to share her with old dudes who pay her (whether he knows it yet or not).
OTOH, not only did I not have to share my shiny young ass apples with others when I was his age, but now I get a second chance to enjoy his as well. Someday, when he gets a bit older, he's going to look back and realize just how much his life has sucked. I wouldn't trade places with him for all the tea in China.
