Hmmm, i agree with silversky.
I have been with some very good looking women believe it or not, but i get bored very quickly.
If they have no personality then i get turned off pretty quick. It annoys me sat in the same room as some dippy woman who doesnt have more than a couple of seconds of convo in them, or who just laughs at everything you say whether they understand it or not.
I think people go for looks first, then if that person is marriage material then they have got to have a good sense of humour.
But obviously, everyone is different.
There are a couple who live near me who just so dopey and miserable all the time, but they have been together over 6 years that i know of...
