I think I've flirted a couple times unintentionally (ahh, the 'fun' of sarcasm..) with some girls before. Other than that, I don't really flirt at all. I have to say, if anyone (aka. a girl or flamboyant guy) started flirting with me, I'd probably get a little uncomfortable. I'm not really that touchy-feely, and I'd probably get a little unnerved if someone started playing with my hair while flirting.
