"What's so civil about war, anyway?"
I dunno if you were being sarcastic about your good looks, but if you weren't, maaaaaaaaaan... for shame, says I. Rejecting the finer gender, basically out of disinterested spite? When they're apparently just throwing themselves at you left and right? I mean, you do realize how much a LOT of other geeky fellows would kill to be in your shoes, y'know? I mean, to be frank, I don't know how un-normal you really are, but uh... based on what you're saying, there's some stuff you've got to work through. I mean, it stands to reason (I think) that if you're flirting, even unintentionally, then somewhere inside your head, your brain is going "Mmm... ladies/gentlemen...", possibly while drooling a little. I know my subconscious is a mess, and I can only speak for what I know.
I guess, I'm just trying to say that, there's gotta be a reason you're flirting, even if you don't recognize it. I've been getting joshed around by my friends for years about flirting with random women, and I never realize it. Personally, I suspect "true" flirting happens when you're not trying. It's a thief in the night, so's to speak.
