Well, I will answer this question by first answering the opposite question. I've found myself attracted to men who have a quality that I didn't find attractive in other men. For instance, I wasn't attracted to excessively tall men until I saw a family friend stretched out under my Xmas tree one morning and wondered if he was a present for me. To get from his feet to his head I had to make a decision: AT&T or Sprint. Until then, I couldn't see how I could have a relationship with a guy if we couldn't see eye to eye. Knowamsnae?
So a man who is so worried about being what I want him to be that he can't be himself (be for real, be honest) is not very attractive.
It's not about how he looks really. When I was a kid, I went for the cute boys. But what a woman wants from a man is different from what a man wants from a woman. A man can look like the last thought I'd have just before committing suicide and still be attractive to woman because of the way he carries himself. For me, it's a quality of imperturbability.
Five things a man should never say to a woman:
1. Hey baby, care to split a drink?
2. Let's go party til we puke.
3. You have such nice skin for a woman your age.
4. Are those real?
and last but not least, the daddy of them all
5. I love your dress. In fact, I have the perfect earring for it.
