I wouldn't mind getting to know a nice girl. Preferably also into the psych. scene, that'd be cool.
I never let girls get too close to me, though, because I'm afraid that a serious relationship would just suck up all my time, and I want to get other things done... I'm not sure that now's the time. I don't know.
That's a really valid concern. It's definitely a different lifestyle to be in a serious relationship. My wife and I were talking about this recently (we got together when we were 18, kids really)... in many ways I think a relationship once you're a little older and have established yourself independently of anyone else (both of you), would be quite a bit easier. But the older I get (I'm 27 now), the more glad I am that I have what I have with her. Because when you're young, being a kid (I was a kid through college anyway, fortunately

), your peers are in general much more open and revealing of their true selves. The bonding experience that she and I had together and with our close friends is completely irreplaceable. The fact that our families got to meet each other when we were still kids, and they got to see us grow up, is irreplaceable too. A lot of people get into their serious relationship/marriage after they've grown up and moved away, and their families can have a hard time getting to know the person who's going to be part of the family. I mean my parents love her like a daughter... she was there for my little brother's 5th grade graduation... he's known her for half his life now.
So I guess I'm saying it's got advantages and disadvantages either way. I wouldn't do it differently though.

But it's definitely true that young relationships can often become codependent and any relationship takes away a significant amount of time that you might otherwise be devoting to building your personal path in life. But then again, you could find someone whose path converges with your path and if you can find out how to work together you could both be even better.
I think that the whole romantic love/relationship/marriage thing happens for a reason in humanity. Everyone influences everyone else... social dynamics between people affects the behavior of both people. The person you're in a relationship with is the most extreme example of this as an adult. If you find the right person, you fit together like a yin-yang... she'll have some strengths that are your weaknesses and your strengths can fill in her weaknesses. You will have a lot of things in common, especially interests, but enough things will be opposite to keep you challenging each other. And it's absolutely essential for you to be close friends with them, not just romantically into them, if you want to have a successful long-term relationship.
