Pretty minor to be honest. I stim a lot, mostly with my fingers...drumming on the table, chairs, head (erm), anything...also wiggle my toes a lot..if I try to stop it...for example...I'll close my hand into a fist to stop it...my other hand will start doing it without me even knowing...if I fist up both hands...my toes start doing it...it's crazy. Also do it with pens, coins, tv remotes,
I do have some sensory things I do. I find myself re-listening to the same tune over and over again very loudly...for hours sometimes...or I'll find a snippet of the tune I like and, again, listen to it for ages...same with TV programmes...if I see a bit I like, I'll rewind it and play it again...again...and again...same with video games...If I find a bit I like...or have an emotional response to I like, I'll replay it...sometimes over and over...
