Men, what do you think when you see a short guy with a tall girl?

That's not that big of a height difference. But what I actually think is that he has enough confidence to not feel his manhood cheapened by his girlfriend being taller. Speaking from a purely biological standpoint, it shows he has the confidence to put aside personal instinct related to ual dimorphism and try to have taller children. And from a sociological and psychological standpoint, it shows that he's not bound by convention. I could be saying this because the idea of dating a girl taller than me is cool in a way (I'm 6'0" so it's like finding a gold nugget in your backyard kind of rare). However, it might look a little unusual if he also weighs less than her (I mean signifficant, not just a couple pounds).
