There's something to be said for both.
I'm average size (recent photo below) although my dick is somewhat large, but large women with whom I've had relationships tended to have negative images about their bodies. They were especially self-conscious about being smaller (i.e. weighing more) than me. Constantly reassuring them that I found them sexy and beautiful could grow tiresome.
Slim women who never had children often had trouble taking my dick deep inside them. I frequently had to be careful not to hurt them; took a little edge off the pleasure. Nothing like laying the full monty on a woman.
Women who see themselves as attractive no matter their size are the most fun to be with. So if you're comfortable with your body you're my type.
