As is probably clear from reading this profile, I consider myself to be an intellectual, but I don't take myself too seriously. Personality wise, I straddle the line between being an INTJ and ENTJ. I can be introverted in large groups, but I enjoy meeting new people. I am a logical person, but perhaps surprisingly, I'm something of a hopeless romantic. Don't take my word for it though — 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. Geeky and nerdy guys are my chosen people. I value fitness and staying in shape and generally date people who feel similarly. Someone who might enjoy dining out, seeing movies, taking long walks, playing tennis, working out at the gym, 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 really loves how much affection I have to give, and he actively encourages me to seek new, meaningful relationships. My partner is totally content with being in a "V" configuration with myself and another person, so dating me isn't much different from dating anyone else, with a slight risk of more scheduling conflicts. If you want to get to know him as well, that's an option, but it is by no means a requirement.
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. Ideally I'd like to settle on an additional long-term partner, but I'm not opposed to having some fun along the way. Also, although I am fully capable of being in two concurrent, full-time primary relationships (and have been successful in this situation in the past), I'm also open to lower intensity relationships with people who might not have the time or energy for a full-time primary romantic relationship.
If you feel like you are too busy for a full-time relationship, but would still like to benefit from affection, romance, and sexual connection on a somewhat more occasional basis — without feeling obligated to be everything to someone — you might be a great match for someone like me.
For a nice primer on the ethical and practical underpinnings of polyamory, I'd strongly encourage you to check out morethantwo.com, which is a very good polyamory resource.
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 writing is going, what I think of the latest gadgets or technology news, or whether I have read anything good lately.
FYI, my "more photos" album contains some pictures that are NSFW-ish, so view with caution.
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 I have a right to plausible deniability in light of the fact that I've changed quite a bit since then (hopefully for the better).
