Romantically, I'm looking for a partner who's intellectual, laid-back, affectionate, and fun. I'm totally fine with just making new friends (in fact, I usually prefer to be friends with someone before dating them), but if I had my druthers (yes, my druthers), I certainly wouldn't mind having someone to cuddle up with for a night in. Ideally, I'd like to find a partner who doesn't take life too seriously, but is still introspective enough to feel comfortable with all the "woo woo" emotional stuff that being in a serious relationship entails. It also helps if you're a bit of a misanthrope. I'm a pretty even-keeled guy, but bright, bouncy people who are full of light and sunshine still scare the crap out of me :P
BUT WAIT, THERE'S MORE!
Scientists, artists, foodies, gamers, geeks, kinksters, and fellow oxytocin-addicts automatically get moved to the front of the line. I'll admit I also place a huge, huuuuuuuge premium on effective and open communication. Book smarts are great, but they don't really make for a solid relationship unless they're backed up with a lot of warmth and emotional intelligence.
So, if that sounds like you... say hello! :)
