In a "normal" situation, I don't stim much. I've switched from biting my nails, to sucking on my teeth, or grinding them. Having a stim "realized" is a real good way to stop it as well. Used to slap myself in the head all the time for screwing up, then someone asked me why the hell I did that. Was embarrased as all hell and didn't do it again. I've noticed a lot of the things I do are disappearing, almost seems to be the result of finding out about AS. I don't jackhammer my legs as much, bite my nails, or do a few other things as much.
As for pain, I used to have my brother bite my arms as a child. Most minor injuries (shooting self with staple gun, air powered) are really nothing at all in terms of pain. Noise is something I am quite sensitive to as well, people around me like to "surprise" me, as they get a kick out of the reaction (generally a f-ing weird spaz thing), but small noises are the worst. People chewing, people talking quietly, and generally anything that breaks what might be perfect silence. Crowds don't bug me, I kinda "melt" into the atmosphere, malls and big huge stores don't bother me either. This seems to be where I break from Aspies...
