What size?

Some people find different people attractive. Have you ever been messing around with your friends saying something like hey dude she's hot, and your friend would say something like ew, no.

Thats exactly like it. One way I could relate is that,

theres this guy in my school, the first time I saw him I use to think he was ugly, like the "i would never ever date him" kind of ugly. once everyone got to know him, he was probably the funniest guy in the world, wasn't scared of doing anything or saying anything, a great dancer too. The thing is, when me and a group of girls were talking about him, we all said "i would totally date him". The thing is, even though he's ugly, we got passed that and got kind of attracted to him by getting to know him, there's actually a lot of girls that like him. He's awesome at dancing too :)

I can't speak on why skinny girls date big guys.

But I have big female friends who always tell me they will not date another big man because 2 big people don't go together. They say it makes the sex more complicated.

I obviously don't think that's the only reason they are together. No one hooks up and is like, hey, you're skinny - I'm big.let's get together lol. But they just use it as a screening. Like a guy who prefers blondes. It doesn't mean he will date every blonde girl or be with a girl just for her blondeness, but his dating circle will only include blondes and he will pick out of that. No big deal.

I have noticed that big men seem to gravitate toward big women though
