Mostly I've dated guys of average to decent looks, with moderate to good personalities. Geeks mostly, but not nerdy, just really into what ever it was they were into. I like a man who can focus on something & talk intellegently about a variety of things. As the comedian says "You can't fix stupid"
I've never broken up with anyone because of their looks but I did dump the one really good looking guy I dated because of his personality. He was a very controlling person & I don't deal well with that. You can persuade me to go along with you but you do NOT order me about.
I don't have a scale. Certainly I am more likely to intially notice a good looking guy, but his personality will determine if I continue to pay attention to him. Unless I have been drinking, then it's all looks.
