Idk why. I try not to be like that and have dated short guys too.
But honest to God, my mother has always put down short men my whole life. She said they have basically a short man's complex and need to be loud so they can be seen, are extremely bossy, etc (sadly that is true sometimes...).
I even said to her what if I married a short man. She didn't like that.
Honestly, talk guys make me feel protected and safe and I imagine doing some wacky ass positions(height doesn't necessarily affect it though). Plus, it's fun cuddling with a bigger guy :P
Short guys tend(from my experience) to have the whole Napoleon Complex thing going on. I know, a generalization but the few short older MEN(30's) I've known in my life have it. And it's even somewhat evident on here at times. Not all short guys have it, but I've witness guys who happen to have it.
But not all girls like tall dudes. There are plenty of girls who like shorter than average guys or who do not mind dating a guy who is shorter than them or who do not have a height preference.
I know I favor tall men because I feel like I don't overpower them! lol I'm a tall, athletic girl so I need a taller, stronger guy to make me feel protected. I like looking up to a man too. Just what I find attractive.
That's really it. I want to be held in his arms, and not him in mine. I've dated guys my height and have had some interested in me-- the height does make a difference. Personality wise? I don't see much of that. Maybe when they're older and bitter, like her age maybe?
