How much to hold out?

[Blarg]

Do you get paid up front?

Although nothing about this situation is remotely likely or realistic, the most likely or realistic way this might happen is if she refused to pay up at the end and laughed at you for wasting years of your life turning down sex and all the relationships that come with it. And not sleeping with you, either.

And the most likely and truthful reaction by the guy would be, "So what? I lied and banged away as much as I wanted, which was my intention from the beginning. But I wasn't about to tell you that."
