I'm actually rather shy, but mostly don't show it or cover it with extroversion.
I laugh a lot, because I find comical elements within many situations. Life's just too lunatic to be taken seriously. Still, I'm not a positive or optimistic person. I just don't see the point in wasting my life by letting negative things ruin my mood.
I might seem anti-social to some people, but I am not. I just don't put myself under the pressure of wanting to "fit in" or be liked by everyone. Neither do I want to stand out on purpose. In public, I'm mostly fine with being let alone.
Within conversation, it's the content that counts for me - I don't like talking for the sake of itself. I always find it fascinating yet frightening that it's absolutely possible to be unable to communicate with each other, though both speak the same language.
I really hate gender cliches, role models and closed-minded attitudes towards relationships of any kind. I'm somewhat gender-queer myself and could imagine being in a polyamorous and/or open relationship (which doesn't mean I necessarily want either one, I'll just take whatever comes and feels right).
I'm also convinced that true love and sexual feelings are two seperate things that don't categorical induct each other.
If I didn't scare or annoy you up to now, I might as well tell you that I have high-functioning autism and ADD. I'm often in doubt whether I should mention this or not - I'm not ashamed of it in any way, but I fear negative reactions or people turning away from me before they even get to know me. Then again, if one is that superficial, I probably wouldn't mind him turning away.
By the way, my user name is a german word for the classic
Mandelbrot fractal. +10 sympathy points if you know what that is without googling it. ;-)
