I don't use orgasm denial as a training tool since I don't have sex with my bottom. It's strictly for my pleasure. I had a previous relationship with a dominant who expected me to save all my orgasms for him, so I didn't masturbate....much. *eg* The reason I don't enjoy chastity is that I discovered the longer I went without the less I was inclined to want it, thereby having the opposite of the effect desired, i.e. constant readiness. We didn't engage in edging. I probably would've used every opportunity to "accidentally" go over the edge.
