I'll be the prick that walks in and rants.
Ladies, I'm not saying beauty isn't possible at any size.. at all. But being big doesn't automatically make one a BBW.
In my personal experience: BBWs are amazing. I know it's never a good thing to generalize, but based on personal experience, they have just connected better mentally with me. Be it because they try harder, or because they really are just better for me it's a personal observation.
That being said, I'll hit on a 110 pounder just as fast as I will a 300 pounder. If you've got eyes and a nice smile (and can hold a conversation for longer than your breath) chances are I don't care what the body looks like. Bodies decay and change, mental prowess and smiles largely stay the same.
