I'm only attracted to fat guys. I played around with some thin guys in my early 20s because I was afraid of what my friends would say if they knew I liked big men. Big guys have the same size penis as average size guys, though some might have a pad of fat covering the first few inches (This can easily be pushed out of the way to get to the whole thing). I have been with two fat guys (upper 300s / lower 400s) who were truly hung (I mean like "OMG, what am I going to do with that!" hung). It was fun, but as pretty as big dicks are to look at, they are hard to work with.
