ISP,
Very good question. For me personally, it's a tough one to answer. Like Sunchild, I like women, but I mostly prefer men.
In a woman I'm more forgiving as far as looks go, because the true beauty of the woman to me is inside. How her mind works, her outlook on life, those are what make her beautiful to me. I can appreciate the "handsome" woman to the "elfin" types. I like the closeness of the relationship.
With men, hmmmm ... tougher still. I like the tall dark handsome guy, and I'm a lot less forgiving. Symmetry is a large factor in what I look for. They have to be in proportion to their bodies, but they also have to be taller than me (no challenge, I'm 5'2). I like the femininity of "goth" guys, and I like the healthier robustness of the jocks. Ultimately it comes down to a combination of looks and personality. If a guy is smart and decent looking, and can make me laugh, he's my type, but if a guy is gorgeous and obnoxious, with no real intelligence, I find him to be a disappointment.
I like men with chest hair. Men should be somewhat manly, while I like women to be more on the feminine side.
Ultimately it comes down to pheromones and smells for me, also. I have to like the person's "scent". They can reek of body odor while working outdoors, but their "scent" is underneath all that. A shower can take care of BO. No matter how gorgeous the person is, their scent is what makes or breaks whether I'll get involved with them. If I don't like their scent, I'll just be friends and nothing more.
That's just my opinions tho. I don't expect anyone to live by them. beauty is a combination of everything that makes up a person you can fall in love with. When you fall in love, it seems like your partner becomes more and more attractive to you.
A perfect way to describe what I find beautiful is how beautiful the object of my attention can make ME feel. That doesn't mean I go looking for ugly people just so I'll look better next to them, gawd, no. I perceive a person to be beautiful when our time spent together makes me feel accepted and more than human. When the bond surpasses looks and goes straight to the soul. Romanticism at its finest.
