That is not nice to say "fat" guy. We are all just people.
And people fall in love with each others pesonalities not looks! Teenagers will probably like a girl because shes "hot" or "cute". But older people dont fall in love because of their looks.
Have you ever heard of "opposites attract?", so the saying goes. But it depends with the likes of the person. Hey, some thin guys see fat girls as just being curvy, sexy, juicy, sensual; she's thick...
Well, fat guys are fat because they simply don't know when to stop eating, or they stuff their plates full and their rule is ""always finish your plate."
