"They don't want to think of themselves as girls who trades sex for money because no one'll think of them as anything else, if they do that, and anyway someone like Carissa or Meritxell's got as much money as she's going to be reasonably be able to spend. I am a girl who trades sex for money, and don't much care what people think about it, so you can trade me money, if it makes you happy.
You're not - running up favors, though, with any of them.. If I met someone and she said, "I had sex with this very powerful rich man and told him I didn't want anything, and then he had sex with me and left and never talked to me again", I'd say, well, sounds like exactly the thing literally anyone would expect to happen, are you expecting to find someone who thinks he thereby behaved badly? You're going to have to search all of Cheliax and find, I dunno, some mournful monk who thinks that denial is the path to enlightenment."
