When you find that you're attracted to someone, is it primarily because:

Definitely the "enjoy each other's company". I've dated men from other cultures, tall ones, short ones, fat ones, skinny ones. Appearance, background, that all has little to do with it. If we enjoy being together, everything else can be worked out.

I'd go for physical appearance (especially the eyes) and personality for short term attraction (e.g. I just met this person five minutes ago). For longer term (e.g. after I've known someone for hours to years), enjoying the person's company and compatible philosophies are more important.
Overall, I'd say the second is more important.

I'm very shallow. I have to find someone physically attractive before I will give them a chance. In the case of my wife I actually wasn't physically attracted first it evolved from knowing her. Probably explains why I married her.

They have 'it', where 'it' is some nebulous quality that is apparently not quantifiable, but someone with 'it' can be picked out of a crowd at a glance. the awareness that someone with 'it' is around does not depend on sight/hearing etc. this of course makes me a complete loon, but 'it' can reside in people that don't fit any of the above categories. There is just something about them. Other than that, I'd have to know someone fairly well to have gotten over my misanthropic tendancies and be attracted to them, and they in turn would know me fairly well (and understand me). phyically attractive is very nice, and if I am attracted to a person, then the appearance is left in the background (or I will focus on the qualities that I like). of course, there are also the times when I am ruled by my horomones, but I don't really want to be that close to a human.... bleagh

this really depends on when I discover that I'm attracted to someone. I can be attracted to someone when I first lay eyes on her if she's stunning, or when she first says something if she's funny, or when I discover she's really easy to get along with when that happens. When I'm attracted to someone, it is invariably a combination of the first 4. I suppose the interesting part of my answer is that I don't need the her to understand me very well or to accept me for who I am to be attracted to her.

Attraction has very little to do with looks, for me. I find people pleasant to look at, but to be attracted to someone I need to get along with them comfortably (some people you can notice this in a few minutes, sometimes it develops over time). The sense of humour, acceptance, and understanding are kind of part of 'simply get along'...

It's a whole bunch of things.

a combination of appearance, enjoying company and common background (which I extend to include similar values etc). If I'm just looking for a fling (which I do, adn I'm not ashamed) then it's probably just appearance. if it goes further than Lust into an actual Attraction, then other factors come to bear.

It depends on the person; different people to whom I've been attracted have been for different reasons. (Primarily 1 and 7--2 through 5 are the bases for interest in a relationship, but that's not the same as attraction, really. At least not as I use the term.)

Numbers one through six, in pretty much equal proportion. (Maybe a little less of number two.)

I can't put my finger on it, things just "click". I think it has a lot to do with them seeming interested in me. I don't like people who don't like me.

I don't known why, it's inexplicable...

This needs to be better phrased. Do you mean an initial atraction to someone, or one that grows over time? Or both? Initial attraction can be based on any number of things - physical appearance (lelle, remember the lead singer from Product? YUM.), something cool that person is doing, saying, or wearing, etc. An attraction over time is more based on a comfort level and how well I get along with someone, as well as a seonse of humor and a touch of wackitude.

I really wish I could pick multiple choices. It is a combination of things.

Usually a combination of most or all of the options.

Of course, in reality it's a combination of things.. Physical attraction can and does happen without even knowing someone (or even seeing them in person!).. That's not the whole picture, for me.. If someone is on the same level as I am as far as sense of humor goes, that says a lot about the person's personality.. More often than not, many other things will match up... ** the point was what do you feel is THE most important thing, initially.. Perhaps I should have phrased it better.. and that's why it's not multiple selections.. I'm trying to see what people feel is the primary thing.. (yes, I know it's difficult.. I'm not even sure I can do it..)

None of the above. If I have to pick a "primarily," I'll go with "because I find them interesting to talk to." *** prefect: we've had 2 similar surveys if you want to check those out.

1-6 not in that order.. no primaries

Physical attraction is often the first thing, because I visually percieve someone before having any other interaction with them. Sometimes I've heard things which intrigue me about them from other people. Whether attraction remains after meeting them depends a lot on shared context, sense of humor, mutual understanding, their personality, tone of voice, hygiene :) I also tend not to be attracted to people I'm sure will not be attracted to me (for instance, straight men, whatever that means)

They express interest in me...

Um... quite a few of them. No one specific thing. Depends on the person.

all of the above - there's no 'primary' cause, it depends on the person. Another one that's a total turn on for me is talent. I can find a person generally unattractive and boring, and then hear him or her play saxaphone, or watch them draw, then suddenly the thing I found ugly is their beautiful unique stunning feature and the way I found them boring is just a quirk or anomoly. This used to get me in all kinds of crazy froth when I was at RISD being taught by brilliant professors and brilliantly talented classmates. It also caused me to go to class pretty religiously.

a combination of the first two at first, then as i get to know the person most of things obtain equal importance

there's more than one thing going on simultaneously.

here's the long version: i've gone out with a number of women, 10 or so, who were stunningly gorgeous--models, actresses, strippers, etc. it never worked out. i went out with 2 women that i wasn't even attracted to at first and after months of friendship, they revealed they were in love with me, and after their revelation to me i found that i had strong feelings for them, too. however, in one case, the woman started doing heroin and disappeared, and the other had a boyfriend of 7 years that she wouldn't leave (and I didnt want to break them up). both experiences left me emotionally battered. so I've given up on the whole relationship thing. that's not really what you asked. so the answer is, for me to REALLY be attracted to someone, i have to feel like they like me.

No idea. Sometimes it just happens. But it's usually based on things other than physical appearance; my perception of their appearance changes to match my attraction and liking for them. There is a certain type of energy in a person that I'm often attracted to, though.

My husband and I have a common background (computers, SurPrize!) ... however, I'm most attracted to him now because he thinks I'm cute, No Matter What!!

Not only do you not get it, but neither do I. There seems to be no rhyme or reason to it. I'm attracted to some people and not to others, and that's as far as I get. There are physical "types" I find physically attractive, but I may or may not be attracted to the person possessing them; alternatively there are actors and actresses I'm attracted to for which the only option that might conceivably apply is physical.

The way they think.
