I never mention anything of my obsession with the piano repertory to girls that I meet. So I don't play for them at all.
It's far too weird for them to tolerate.
"So all you do is practice the piano for hours a day, huh? That's nice.."
(even though I've long stopped practicing for long, mindless, and ineffective amounts of time, they assume that because I have few 'other interests')

EDIT: I seem to have missed the point of this topic. I really don't think that piano playing alone is going to win you girls. Being an artist is an quality that makes them you like you more after you've already gotten them to like you as a person.
