Martin001,
Its a game of numbers, the girl likes this, she dislikes that. I'll give yout he honest truth, you're shorter, one strike against you, you're shorter and you're intimidated by it, two strikes against you, you're shorter and comfortable with it, no strikes against you.
Here are the facts, YES, women like taller men. If they could pick between you and your genetically engineered 6' tall twin, they'd pick your twin. But if you're there next to some tall guy and you are more confident and interesting, then YOU will close the deal, not the other guy. What concerns height, women interpret tall men as more confident, attractive, better to protect, manly, driven, and possibly succesful. But! All that doesn't mean shit if a tall guy comes in there and fucks it all up with his clueless ways. By being shorter, you may not be the first guy to be checked out by ladies, but thats irrelevant, if you stay here and learn you're the one who's leaving with them. My friend is 5'4-5'5 and he gets plenty of women (tall ones too!).
Which leads me to ask, how tall are you?
