What is this scratching trigger I keep craving? [Question]
I love scratching. There's a trigger I keep craving deep in my soul and I don't know what it is. I've tried different videos where people scratch trees, concrete, steel wool, bare mic, scratching post, carpet and they ALMOST meet the craving. The scratching is not "deep" enough but the closest I think is bare mic and rarely some wood scratching. Please give me ideas or you own triggers.
