I think, for the most part, unless you are very fat or extremely skinny is basically irrelevant. For girls, looks aren't everything. I must admit, me being a guy I don't care about anything else, but girls look for powerful, fun, outgoing, interesting men. Unless you are on a beach or something, most of the time your physique does not even matter. However, just like some girls are into black, italian, hispanic guys etc.. I know a fair share of ladies that just love big muscular guys. The thing with girls is that they all do not prefer one thing. Us guys we see a girl, and almost every guy in the room knows if they are hot or not. With girls, it's a different story. One girl may think a given guy is gorgeous while the next one may think they are ugly.
