I've been breaking a lot of rules with this girl.

Generally, if I don't have sex with a girl on the first or second encounter, I'm done. I never buy drinks, I never take girls to dinner, and to be honest i've had a pretty good year (22 F-closes). But for the past 2 weeks, i've been seeing an HB9 whose making me break all these rules. Granted, she's had a pretty good excuse for going home every time, but tonight marks our third date with no action. Heavy making out, kino. Hell, she even had her hand on my crotch, but when I said "lets go back to my place" she said she had to work that morning, and we should meet up Sunday instead.

I know this example is just one girl, but in general, when do you move on? I think that this particular case is a lost cause, but i've already passed my personal dating limit.

What is it for you? One encounter? Two? Three?
