Thoughts? Might tick some of you off. Might not.. Let's see

So a guy I work with I'm starting to like.. Kinda. A lot. 
(I'm 21 so if I sound like a little girl I apologize, I haven't crushed this hard in awhile). 
He plays guitar. So well, and also sings AMAZING.  He's also really funny. Like GENUINENLLY funny 
The thing is.. He's shorter than me (a little) and also fluffy (chubby,fat). 
But I feel like.. It doesn't matter. I've never even been with a bigger guy so idk how I feel about this.
