Uh, i like rocking I don't even bother trying to stop myself around other people anymore. Heck, it helps me to relax and focus, and i don't see how it would bother anyone around me, so i do it.. It usually starts without me thinking about it at all, but when i realize i'm doing it i usually don't stop. As for something i'm usually more aware of doing, i really like picking at the skin under my fingernails... And cuddling with, petting, and smelling my dogs, if that counts as a stim(whatever it is, i find it very stimulating to my senses. i love the feel of their fur). And i generally like to repetitively fiddle with whatever interesting little object happens to be around at the time, but i don't think that's very unusual.
By the way, labpet, i do that thing with holding and pulling at the bottom of my shirt or jacket also! I usually feel like i should be doing something with my hands when i'm standing, so when they aren't in my pockets or fiddling with something, that's something i tend to do a lot.
