One that always calms me down if I'm in Sensory Overload or just stressed out is gum in my mouth. There's just something about the full feeling in my mouth combined with the chewing motion that just delights me.
I hate the feeling of lathery/sticky things, such as the liquid that you use to blow bubbles. I was helping my little cousin blow bubbles today, and he spilled the bottle on to my hands by accident...
