My typical stim is the standard finger flapping that I have read about since joining this site. I never thought much about jewelry and stimming. I often lightly tap my earring twice every so often. It has to be twice, probably an OCD thing going on there. I don't know if that's more out of stimming, habit, or checking to make sure it's still there. I think it's the latter. I do on occasion play with my toe ring in a way that might be considered stimming.
