Big Big Love.

". . .a lot of people  . . actually feel sexier and more self-confident when they are bigger . . . For some people, it’s as simple as the fact that when you’re fat, especially when you’re fat to a certain degree, you know from the get-go that you’re not going to fit into all of these idealized versions of what bodies are supposed to look like, and so you just stop letting that register on your radar. You can just concentrate on enjoying your body and enjoying your partner.

Another thing that comes up for a lot of people is that fat bodies are really sexy and sensual. There are a lot of textures and there’s a lot of skin and surface area, and a lot of sensory nerves. Everything that you’ve got on a thin body you’ve just got more of on a fat body."  The joy of fat sex By Tracy Clark-Flory  
I have to agree.  I like women who can put the hay in the barn.  Rubens trumps Twiggy every time.
