In this case, you are changing your whole desire. It's not Pavlovian. It is a trained response, but born out of conscious practice, not subconscious pain avoidance. It's still effective, as you have experienced. I personally avoid sex and even arousal, because of the negative effects I perceive accompanies. It's a delayed reaction (about 12 hours), but after I made the connection I quickly decided that O, even legitimate O with my wife, is not worth the repercussions. Still working on that autonomic response, but I'm getting there. How is this even possible? This stuff is darn near instantaneous for me. Maybe I should tighten up my parameters?
