Why am I only attracted to persistent guys?

I hate traditional 'flirting' - this whole idea that the girl should give the guy 'signals' and 'encouragement' like eye contact and smiling, so that he'll come talk to her. I believe that I shouldn't have to play games like this - if a guy wants my number and really likes me, he can approach me without any 'signals'. Whenever I see a guy checking me out, even if I think he's really cute I'll always avoid making eye contact and pretend not to see him, as I want him to PERSIST. But they almost always give up. Literally only one guy (yep, just one) in the past three years has approached me anyway. I wasn't even that attracted to him at first, but because he wouldn't take no for an answer, he really grew on me. Things didn't work out, but I have no idea when I'll ever meet a guy like that again lol. Does anyone else experience this?
