My girl's slightly overweight to the point where she doesn't look at all fat but when she bends over and lets me have her from behind it's like "wow, that's a biiiiig ass" (in a good way). But I'd say weight in general is a case of suiting someone. If it looks okay, complements them somehow, or otherwise doesn't show all that much, it's no big deal. Some larger people are very attractive. But of course, there are the people that really let themselves go, and that's more difficult to justify. Still, that's not to say they can't be lucky in love - there's someone for everyone regardless of size.
