Then again, perhaps I am being too pedantic, so I'll try to do both.
First of all, despite how it may seem above, I do not take myself seriously, and I do not get along with anyone who does. If you are pretentious, and can't laugh at yourself... Well, lets just say, I like people who can take a good-natured ribbing from time to time. The best kind of friends are those who can throw playful insults back and forth at each other without getting upset or sensitive.
The best one-word description for me would be "curious". I am curious about the world, the universe, what makes people tick, what's around that street corner. I also adore sharing that curiosity with someone, and I want someone who will enjoy exploring the universe with me.
I am someone who can enjoy spending the day marathoning a TV show, but I get anxious when entire weekends pass without a single reason to leave the apartment. I want someone with free time enough to go out for weekend adventures with me, even if it just going to see a movie, or walking around Boston, or some North Shore town like Salem, or less touristy areas.
In the more relationshipy areas, I suppose you could say that I enjoy a lot of contact. Cuddling with someone cute (even if just a cuddle-buddy) is about the best thing in the world. I also have a rather large libido, but that is fortunately, or unfortunately depending on who you ask, balanced out by being inherently respectful, considerate and non-aggressive. I'd say I am very "open-minded", but not crude.
To sum up, I am an intelligent, clever, curious, and considerate guy.
