Primarily right-handed. I use it to write, draw, etc.
Except when it comes to computers or sports. Then my left side is dominant. If my friends want a laugh, they used to watch me try to use your average computer mouse with my right hand. It would just veer off the screen, then shoot across. For some reason, I used to have no control over it, but at least I have a little now. It's not very comfortable, though. Again, in sports, my left arm and leg are my launch ones, not the right. I'd guess I fall a lot more when I start on my right.
But when it comes to things like hunting, I'm right-handed again. So it's almost like being ambidextrous without the convenience of being so in the same field. : D;
