Ultimately, if you can deal with them at their worst. Even at someone's best, if they follow some religion or are conservative in politics, I'm not sure I can deal with them. But if the worst thing is they fart at inappropriate times or let dishes pile up in the sink, I can deal with that.

Because if you can handle their worst, then you're going to think they're amazing even if they just got up, have bed head, no makeup, and REALLY need to brush their teeth.

The main thing I look for is a willingness to compromise. Someone who's incredibly stubborn and selfish, has a my-way-or-the-highway kind of attitude, will get nowhere in relationships. No two people are going to agree on every single thing. So someone who's willing to sacrifice, and relinquish their pipe dream where everything go exactly their way, and agree to a situation that's still really really good and one where both of you can be happy, is someone for me.
Of course it would have to go without saying that I would be willing to do the same to preserve a loving relationship.

Intelligence. Confidence. Physical attractiveness. Credit score.

Racism, Republicans, closed minds = turn offs
Being pursued, looks, deep voice = turn ons

Someone who enjoys spending time with me, thinks I'm funny even when I'm not, truly believes he's lucky to have me? Will be the luckiest guy in the world. I love with all that I am, I don't know any other way. Sometimes I think I'll have to have plastic surgery and dye my hair blonde to find someone who thinks I'm cute, but I would rather be alone than be anything less than true to myself. I want someone who feels pretty much the same way.

being honest , heavy drinker who say hateful things.

Common interests, physical attraction, patience, kindness a desire to be physically active and eat healthy.

Intelligence, empathy, emotional stability, cleanliness & a dirty mind are all good.

Compatibilty first.
