Your sentence structure. It needs work.
I used to play-flirt all the time. ALL the time. With EVERYONE. Which, of course, meant I missed quite a few opportunities of actual flirting, as it turned out, so much later.
Then again, it also got me in bed with my current girlfriend while I thought I was just play-flirting because I didn't figure I'd have a shot with her, so hey, it evens out, I guess. This is also why I'm not allowed to play-flirt anymore
