A stunning woman who has a bad personality is not sexy at all. Brains are sexy. A good sense of humor is sexy. Empathy is sexy. A woman who has a value system similar to mine is sexy.
Creativity is sexy.
All of these things are more important than looks. A woman who is mean, or stupid or violates my sense of morality is not sexy at all, no matter how good she looks. I think that physical attributes can be overlooked if the person has a great personality. Besides, we all end up fat and ugly. Looks are important because they form the basis for physical attraction.
