I'm a bit of a sapiosexual, attracted to highly intelligent men with a great sense of humor.

Sense of humor!

Refuse to vote on physical attributes. When I broke up with my last longtime partner, I asked him to name 3 things he liked about me. All 3 were physcial attributes. He didn't need me, he needs a blow up doll. Give me an honest, honorable guy who can have an intelligent conversation. Then he can reveal to me his unique various unexpected character traits that sweep me off my feet, like being kind and generous to others, showing grace, respect and admiration to those who deserve it, etc. A person who does a good deed or shows a courtesy to a stranger will catch my attention.

A real genuine smile will get me every time.
As for most important... Personality, and it would have to include honesty.

They're personality.

A sense of humor with a good dose of sarcasm.

for me it's teeth... i have a friend who seems to go for any woman... his current g/f has no teeth to speak of and the ones she has are black. there's no possible way i would date a lady with black/missing/extremely discolored teeth. i don't have the perfect teeth but at least i have most of them and they are whitish.

Eyes. If a woman can smile with her eyes she'll melt my heart, I'm a sucker for smiling eyes.

Smell is a big component of attraction. "When we meet, we ought to walk around each other, sniffing like dogs," I joked to new men over the phone. I was talking about pheromones. Alas, men rarely got the joke, so I dropped it.

"I'm sorry, Bruce, but it's just not happening," I said when Bruce wanted to have sex with me. I love the guy! A master-degreed counselor, a former Baptist minister who is now an atheist, Bruce is hilarious, warm, highly intelligent and wise. We had fun singing together. But he doesn't smell good to me.

Raised in Lousiana, Bruce has two deep fryers in his kitchen. (I stopped eating deep fried foods 40 years ago.) And he tends to be overweight. Don't know if it's his diet or body chemistry. It doesn't matter how many showers he takes. I could never tell Bruce that his smell is off-putting to me. It would be hurtful.

Actually, eyes are the second thing I notice. What attracts me the most is there personality.

Their hat.

A lot of times I'm not attracted to someone until I talk to them. If they are witty and funny then they catch my attention.

Their brains. Pretty won't cut it if they're dumb, but a woman who can engage my mind looks pretty to me.
Hard to find out on the first meeting, which may be why I make relationships over dinner with friends rather than in bars.
Being less than beautiful myself may be a confounding variable.

That would depend on which way they're facing. All of the above, each in its own context and time, though I voted in favor of a nice, curvaceous posterior.

Intelligence is the hands-down winner, though. Nothing beats a great mind.

Voice

The physical is all we have to go on initially and the smile IMO is the most telling. Now once he opens his mouth and talks that's another thing. He should be kind/caring, smart, witty is a plus, upbeat (no grumps), playful is a plus, and then chemistry. The physical is last because a plain man can become completely knockdown gorgeous if he has a personality to my liking.

Smile

None of the above., after of course 'chemistry' which isn't visible.

I'm attracted first to the 'music' she makes with her body and face while moving, gazing back and speaking; her body language. Intellect and character are vitally important. Unless she's emaciated, morbidly obese or unclean and ungroomed, the rest doesn't matter that much for cultivation of friendship.

For intimacy, deep respect, admiration, trust and love. The greater part of beauty cannot be seen by the eyes alone.

The eyes get me first. Then the smile.

Attitude.

None of the above. For me it is how they are dressed.

Hair. I don't give a second look to blonds. Plus, I spend a lot of money on maintenance and don't want any judgmental remarks.

I am most attracted to an intelligent assertive woman.

The person who is kind emanates that value. I am attracted to intelligence, composure, and spirit.
