I'm in no way part of the BBW-cultus, since that's a political correct euphemism for a paraphilia of its own. I also happen to notice fat women having a high temperament, whenever you don't consider them beautiful. Often happens.
I usually leave them in their value though, as there is a public for them. Bigger, heavier women can be beautiful, but I cannot imagine an obese woman being so. Not in my book, in other's books it's possible. A good thing for these women, as long as their health allows them to enjoy life. Healthy food for the win!
