I really doubt that you won't prefer man looks like Jaime Lanninster rather than Iron Bull face. Iron Bull is ugly and in the real world women won't choose him over good looking person. Bull even has horns and he sin't human. Even Cole is prettier.
Blonde haired pretty boy Jamie Lannister? No, I wouldn't prefer him. I happen to be a woman and out of the two, I happen to find Iron Bull more of my taste.
Plus, you forgot to mention the most important part: Jamie Lannister is a douche that among other things, tried to kill a child by pushing him out a window because he was screwing his sister and said child caught them.
I don't give a crap what someone looks like if they are a jackass, or a horrible person.
I don't find Cole attractive because, just going by looks, he looks like an unhealthy man bordering on nearly corpse-like.
It's fine to have your own opinion, but you do not speak for all "real world women," nor should you assume to know what an entire gender thinks. Knock it off.
