Well, I don’t know…Intelligence has shown up on just about everyones list so far. I can still se your point though. I think here are three types of intelligence: street smarts, book learning, and common sense. I suppose a guy that had all three would be in greatest demand, but common are those?
A point raised all too rarely, I fear! 
What FairyChatMom said. A nice dick doesn’t hurt, either.
The most important thing for me, the one that caused me to leave my almost-fiance for another man, was: Does he know what I consider important? In general terms, that is. My best male friend knew me far better than the guy I was planning to marry, and when I realized that, I realized I was dating the wrong guy.
Granted, that takes some getting to know the person, so initially I’d probably say: Intelligence, wit, common interests … and being easy on the eyes helps, although certainly isn’t required.
Oh yes, all of that. But for dessert, I need the Karmic connection. You know, where you look into each others eyes and just know that they are the one. The chemistry, the oomph, the charisma, the melts you with
one glance and you feel all tingly inside, the I’m starting to perspire, I’m breathing heavy and I feel faint, the come-here-big-boy-and-give-it-to-me-straight-I-can-take-it stuff.
That’s not too large an order is it?
Not for a Danielle Steele novel, anyway. 
Back in 7th grade several of my friends & I were discussing our Ideal Husbands. They went for tall, dark & handsome, but I wanted 1) at least as intelligent as I was, 2) good sense of humor, and 3) able to fix things around the house–after which I wanted 6 ft, black hair, blue eyes. Even at 13 I knew what was important!
Never changed those criteria; didn’t even consider Aglarond’s Assumption. Married a somewhat overweight 5’8" brown-haired, brown-eyed wonderful guy to whom I was first attracted by a quietly wicked sense of humor. He also met criteria #2 & 3, plus damn near everything on Dogzilla’s & Edwardina’s lists. AND had a sharp knife, and other satisfactory equipment. Was always somewhat amazed HE wanted ME.
If the guy has all the important stuff, Aglarond, the size of endowment is pretty damn irrelevant.
Is the sharp knife for peeling apples?
…realize I meet NONE of the criteria (I don’t even like to play with sharp knives),
…sigh,
…and say to myself “At least by being celibate, I won’t catch a STD.”
