The whole idea of a woman paying for sex is not that she can't get it for free. Unless you're really hideous, most women could get laid by 5 different guys daily. The point of paying a man is walking into a room, having the men line up, pointing to the one you want, and saying yes, I want that one, and spending a certain amount of time having him do EXACTLY what you want and then leave. It's not about getting sex it's about having power over a man. Women are used to having to play the nice girl, making sure we don't give it up too soon to ruin our chances of it turning into a relationship, we have to act a certain way, stroke his fragile ego, make sure we don't come across as too demanding, or too slutty, or too experienced or not enough. It would be kinda fun to just say "do this, do that, bye bye!" If we are talking about a fantasy world where the guy is squeaky clean and I couldn't get any kind of disease and he looked like, let's say Mario Lopez, then yeah why not!
By the way the only thing that would really make me feel weird and sad is if I had to pay a guy for his companionship. Now THAT, is depressing to me.
