To truly understand the things you expect of your sub and to be justly competent to dispense punishments safely, there are things you need to remember. However there is no better way I know of widening you knowledge of sensations and the link with pain and production of endorphin's, than to become a sub yourself and experience things from the other side of play. I have a higher than average tolerance to pain, so this is an easy thing for me to do although alien feeling as I am doer as opposed to a receiver. Here are a few photos showing me in the submissive role which I am quite a handful as.
