I prefer muscular to "thick" bodies on men. I even prefer "fat" men to men with "runner's bodies."
i think a big muscular man signifies masculinity, and comfort. its the whole defending your honor, conquering the world for you idea. i need a manly man....a brute. they are messy as hell, and sometime ignore you while watching football...but they do the damn thing. they take care of business. they give the best bear hugs, they are so snuggly, and they make great dads.
My dad is a rather large, masculine man...i guess its true when they say girls marry someone like their father.
