Me and my coworker flirting? Yuck?

Me and my coworker have lowkey been flirting, or maybe I’m misreading it. He (physically/attraction wise) is NOT my type. I feel like looks really do matter when it comes to attraction, it’s all about preference.  His hair is greasy, shows he doesn’t really take care of himself, his beard is overthrowing, and he seems to weigh a bit over.. nothing wrong with that, again, preference. I want someone who works out, maintains their looks and takes care of themselves, it proves to me that they’re capable of at least that, which can show a lot. Maybe I’m just TOTES an asshole :(  IDKKK
