Heheh, not really a ton
And then when I do its usually without meaning to cause if I ever did it purposefully I'd suck at it. Though if I'm around a guy I usually become much quieter than usual, mostly cause I can't think of anything to say, unless I know them really well.
Though right now I think the guy I'm going out with right now would probably be a bit upset if he thought I was actually flirting with someone (not that he'd say it, cause Asian guys around here seem to be like that.)
