'men without' is a broad term, are we taking about guys in good shape but not very defined muscles? or are we talking about men in bad shape, kinda flabby.
Personally I believe men are the same as woman, in that they shouldn't be objectified by the opposite gender or by social standards. Chances are, if you like a girl and she doesn't like you because of your physical flaws, then you should count your blessings because she was likely not the one for you. The kind of woman you should look for is, as I like to put it sometimes, a 'Belle' (yes, I am getting all Beauty and the Beast up in here); a Belle is a woman who looks past your physical self and likes/loves the person you are inside.
But I suppose to answer the question more directly, I do feel most woman prefer a well sculpted male. It may also stem from survival instinct, more fit looking male = more likely to survive, survival of the fittest logic. But as Falcon said, it depends on the woman.
