It doesn't have anything to do with strength, but people think that it does. Listen, if some 5 foot guy was trying to mess with me, I look down and laugh. If some 7 foot guy was doing the same thing, I would NOT be laughing. By virtue of me being tall (six-four or so) nobody EVER tried to mess with me, even though I was always week and a little skinny.
Anyway, I am not even certain that it is strength or whatever. All I know is that I probably would not want a girl that is taller than me. Yuk!
Dude, if you are short, that is fine. Many people that I know (almost all) that are short, go through hot women all of the time.
Women may SAY they like a tall guy, but go through them to see if they actually stand by thier word. Who cares about the ones that don't go for you because you are short, find one that doesn't care. They are out there.
