Emotional pain just makes me cry. If it's really bad, I'll sit and sulk for a little while just to stew, then get up and move on with my life.
Physical pain... um. I'm an abuse survivor, a former self-injurer, and a masochist. Pain doesn't bother me unless it's something deep and lingering (like when I pretty much destroyed my left knee). If I'm bleeding, it's a bit of a bother, but generally I can just breathe through it (I sliced into the pad of my index finger while at work, and it wouldn't stop bleeding. So I slapped a bandage on it, grumbled whenever it hit something, and went on with my day).
Deliberately inflicted pain (no need for details) is a delight to me, and I'm quite all right with that.
