I'm currently single, and I LOVE it. Sometimes I think about being in an actual relationship, and that kind of stuff but the bottom line is, I don't want to be bothered. I enjoy being alone in my house, and can't imange sharing it with anyone else (...other than my family, I currently live at home, but taking steps to be out on my own).
When I get lonely I have friends I hang out with, which I'd honestly rather do than a girlfriend. And yes, there are those "certian needs" that I have every now and then, but I can take care of them myself.
Honestly, the only things that would make my life perfect right now would be advancing in my job so I can comfortably afford my own place, and a fuck buddy for those times when I need "some"...
