This mostly happens when I'm washing the dishes. The sensations are much more intense when my nails touch the sponge - and as a reflex, I often have to pucker my lips or weirdly move them in order to get rid of it.
I randomly spoke to my friends and family about it as if we were cut from the same cloth(thought they experience it as well) and they looked at me as if I was crazy.
Couldn't find much on google, and I'm really curious about this - any insights?
