I’ve been put out from a chokehold but not from smothering although I have been smothered. In my experience being put out from a chokehold is like being put to sleep as the pressure on the carotid? artery increases. Kind of like when you are put out from anaesthesia. Very peaceful. This is as opposed to being smothered as you can feel your air shut off and you are unable to take a breath which induced panic.

I was a regular of a Domme who would facesit and smother me. When I panicked she would repeatedly whack my hands as if to tell me to no be still. It was hard but I learned to relax and let go and trust her. She always stopped short of making me pass out.
