Polar opposites

Okay so normally I like these girlsthat are total bitches and stults. They are so fake they plaster on the makeup and look and act so fake it makes me sick! But they're a lot of fun, and that's what I've wanted just some fun.
But a few months ago I saw this girl and she's a little bigger than some most of the girls I've ever gone out with before but she is actually very beautifu, she has ligh brown hair, dark brown eyes, big red lips with no makeup on at all, she never wear any makeup at all but yet she always looks beautiful. She's also very sweet and kind, she would never hurt a fly. She also very shy and self concious and has a pretty low confidence. She's so unlike the girls I usually date. And even if I was to actually like a girl I would've never imagened it would be a bigger girl that was shy and very down to earth. I thought it would've been someone more like me loud and outgoing.
So is this normal???
