I ordered my MGX yesterday, and thought I'd say a little about what led up to it.
From my journal entry of July 6, 2009: Just did a sexual meditation. I was exercising my PC muscles while lying on my back. I was giving my attention to the way my PC muscle was working. What I could and couldn't do with it. I soon became very sexually aroused. I decided not to touch myself. To see where this would go without hands. I found the experience as intense as some orgasms, though it wasn't really an orgasm. Just intense. Anyway, I got up from it saying that I have to give that to myself again soon.
I had taken a Tantra class a few years back and we were given an exercise to do. We were to sit and contract the PC muscle for about five minutes. I did the exercise faithfully every day for three or four weeks. At no time did I experience any sexual energy. On a single contraction maybe two weeks into the practice I felt a very slight twinge of erotic feeling, but before and after that – nothing.
