Depends on how you define BBW... To be there is "skinny" then average, then chubby, then fat, and finally HUGE.

I actually prefer chubby (like 15lbs - 20lbs over what would make one "skinny") but I wouldnt find women over that sexually attractive... Though to be honest I have banged a few fat girls! But I'm a guy so it isnt necessarily all about what I find sexually attractive... Sometimes its just about fucking. Still dont prefer the big ones but if it's between sitting at home alone watching TV or fucking I'll usually go with fucking.
