I could be wrong, but I think the pushing in a reverse kegel is kind of unnecessary if you can will the relaxation of your pelvic floor muscles. I was edging for a while noticing how jumpy and twitchy my BC muscles were getting. I played a funny mental trick where I was imagining the muscles (deep inside the muscle even) being slowly massaged in a relaxing way by something soft and white, and any tension was dropping/leaking out of my body. I sustained that for a while and got harder as a result. Every once in a while a twitch would come back right before being told to relax. I would think that the parasympathetic impulses fighting for dominance, which also made my dick harder.
I'm wondering if all the MMO masters and tantra masters just have trained their ability to saturate their nervous system with parasympathetic impulses as the dominate automatic response.
I've had a some DO before, (mostly half DO and a few without any leaks). But they don't have any more feeling than a normal orgasm with ejaculation. I think training the parasympathetic is key, while edging and maybe reverse 'pushing' kegels too are ways to train the elevation of parasympathetic responses. Stretching, mental visioning, pushing the sympathetic responses without hitting PONR all seem to get the parasympathetic side some training. After all stretching isn't actual stretching, but actual training of your nervous system to relax.
Anyone think those thoughts have merit?
