Multiplicity

I agree with this method, I have DID MPD which ever you want to classify it as and I have two major alters that cut, one really bad and the other not to often only when they have problems in this life and the alter that cuts bad is down to just scatching the surface and it satisfies him, or if its not just scratching the surface its laying a blade that has a girated edge to it and just pressing it down into the skin until they felt the pinch in the skin and that satisfies him too. I agree with your method here.
