I consider myself to be an intellectual, but I don't take myself too seriously. I can be introverted in large groups, but I enjoy meeting new people, and I try to make sure the people I am with are having a good time, which I accomplish through a combination of wordplay, witty banter, and scintillating conversation. Or just doing something dorky. Hey, whatever it takes.
Personality wise, I straddle the line between being an INTJ and ENTJ. Suffice it to say, despite my proclivities toward reason and logic, I am actually a hopeless romantic. But don't take my word for it; I strongly encourage you to find out first-hand. ;-)
As far as dating is concerned, I enjoy the company of those who are fairly smart, intellectually curious, and who have a good sense of humor. Someone who might enjoy dining out, seeing movies, taking long walks, playing tennis, attending book readings, traveling, visiting anime/scifi/comic/? cons, playing the occasional video or computer game, and having techno-geeky conversations would be great, but I am open to suggestions, and I love trying new things. I should also say that I am a warm and affectionate person, so casual nights in spent cuddling and enjoying each other's company would also be nice. Low key evenings can be wonderful.
I'm a practitioner of ethical non-monogamy / polyamory, and I am happily partnered with a wonderful guy, but I enjoy meeting new people and making new connections. My partner actively encourages me to seek new, meaningful connections, and there are no limits on what others can achieve with me romantically or sexually; rest assured, I don't have second-class relationships with anyone.
You can feel free to keep reading if you'd like to put up with my logorrhea, but you can just as easily skim and get to know me through conversation. For starters, you can ask me how my research is going, what I think of the latest gadgets or technology news, or whether I have read anything good lately.
Finally, a disclaimer: I answered most of the OkCupid questions 2-4 years ago, so I reserve the right to disavow any answers that seem disagreeable. I think plausible deniability makes sense in light of the fact that I've changed quite a bit since then (hopefully for the better).
