If we are talking fat and unshapely, then no. I've tried. My equipment just won't cooperate. This does not mean I cannot find larger women attractive, because this is not true at all. Shapely women come in all sizes, from really petite to full-figured.
I'm not going to find a girl very attractive at all if her physique doesn't give off at least a little bit of flare that says she likes to keep things together, regardless of her size.
