Bum by far and wide. I can look at a woman, talk to her, spend the whole day with her even, and never so much as notice her breasts. But I find myself mesmerized by the butt of every hot chick that crosses my path. It's the first thing my eyes run for.
I'm with this.^
I'm a butt man in a boob obsessed nation - a stranger in a strange land.
Some of the sexiest girls I've ever known or seen had small boobs (almost flat chested), and they still did it for me... if they
did it for me.
I'm just not so fascinated by how big or small, or what shape a girl's boobs are. But I'm REALLY into hips, butts and thighs (the package). Wide and flat, no! Narrow and flat, absolutely no!
Even my girl accepts that if we're at the mall and a girl with a nice butt walks by, I'm going to look. I don't glare like Chester the Molester and embarrass her. But I'm going to take a good, quick mental snapshot. But boobs? :dunno: I might glance if they're silly big or bouncing in a tube top. But I'm just as likely to not really notice.
