I have many different thoughts on this, falling in love, what particular traits in another will initiate it in an individual.
I think everyone has certain physical characteristics that particularly attract them, and, as you say, I see no problem with that. Just as one may be attracted to a certain sense of humor, why wouldn't the same individual be attracted to a certain physical type? But, as you say, there are things that over-ride simple physical attraction. Personally, I am attracted to women who are tall, athletic, nice hips, and so on. Saying that, there have been many instances in the past where I fell hard for someone who didn't match those things at all. One of the women I fell hardest for, with her becoming an obsession during our time together, was not even 5 feet tall, as she would say, "4' 10" and a half." She always stressed the half-inch. I say I'm most attracted to women close to 6 feet tall, and I fall head over heels for someone no where close to that.
What was it about her that overcame what may seem her physical deficiencies? We talked. Really, it's as simple as that. We were, in a sense, misfits within the area in which we lived. Much of the population was very narrow minded, having no interest in pursuing anything outside of what was known to them. She was not like that. We talked about writing, traveling, anything either of us found interesting, things we could share with few if any others. We found ourselves to be much more alike than different, each of us finding a bit of a safe haven from the confusion of the world, the area, in which we lived.
Although she was much shorter than my ideal, she was far from unattractive. She did have a beautiful body, but I likely wouldn't have taken the time to notice except for the intellectual qualities that seemed to draw us toward each other. The connection we shared was so strong that now, sixteen-years later, I think of her, remembering certain things, and smile.
I continue to maintain my preferred physical type. But, through past experience, I've learned there are often many exceptions to every rule.
Sabina asks: Are there any absolute taboos for you? Things that, if you see them in another person, the attraction immediately falls apart?
There are many things that will turn me off from someone I may have initially felt attracted to. Reading this question, one instance in particular popped into my head.
There was a woman I was attracted to. She was pretty (as I see it), fun to talk to, and athletic, being a star on the university softball team. We talked and joked, a mutual attraction growing. We had spent time together, but generally among other friends. Finally, we went on our first official date. We went to eat, nothing too large, simply grabbing a bite before seeing a film.
I don't remember which film it was, but in one scene, two of the male characters kissed. They were fully clothed, nothing explicit, simply a shared kiss between two people in love. My date's reaction of, "Eww," told me more about her than all of our talks up to that point. I could understand if she were bothered by it, two men kissing being new to her, if she had at least been willing to consider there was nothing wrong about it, if she had been willing to question and get past the prejudices she had learned. I mentioned the scene as we drove home after the film. Her reaction was basically still the same. She wasn't so much bothered by it as it being wrong but simply was unwilling to question or think outside the box of prejudices she had brought with her to college.
We remained friends, but after that night, I felt no attraction to her in any way.
I maintain certain preferences, physical and intellectual, but I've learned there are exceptions to pretty much any rule.
