I hear it all the time as an adult man. The traditional chauvinistic question - "what kind of man are you? Are you a tits man or an ass man?". And all the time I sit there and think "why do I have to pick one of the two?" Can't I be attracted to something other than those baser physical characteristics?
I guess the real thing that I'm attracted to in a woman has to be her mind and how she "handles" life that happens. How well does she "human". That's what I'm attracted to in a woman. But I know most guys are looking for a physical attribute, so here's my answer. If I were to pick a physical attribute above all others I would say a person with a beautiful and kind smile is what I am most attracted to. Why is the real question... WHY is that what I'm attracted to? In my belief a beautiful and kind smile can only be faked by the truly deceptive, and I choose to believe that a trusting and kind smile is truly a trusting and kind smile... Especially when it's backed by behavior and actions that follow their demeanor.
