So I'm starting to have a much better grasp on the role that orgasm plays in relationship but I'm still having some areas where I'm having some difficulty and looking for some perspective.
First, I was able to go almost six weeks without an orgasm and during that time I felt very stable emotionally. During that period I don't think I had intercourse with my partner but once or twice and it was a very gentle form of Karezza when we did. However, in the last month or so I've fallen back into a "typical" frequency (1-2x/week) and with that the moods have become less stable (as Marnia's theory would predict).
I've attempted to do Karezza again but even with Karezza I have an almost impossible time not getting over-stimulated. I can hold off on having an orgasm during sex usually but then I have a feeling of sexual tension that exists until I release through orgasm. This is likely due to the fact that during "Karezza" there is more thrusting/friction then there should be. It feels really good at the time and even feels OK not to orgasm but the build-up in stimulation makes it nearly impossible for me not to seek release at some point.
So basically what I've come to the conclusion is that I can do a "no stimulation" abstinence period from orgasm. That was actually a lot easier than I thought it would be. Or I can do traditional orgasmic frequency and just learn to live with the mood swings. But to experience stimulation through intercourse without being able to orgasm seems really tough.
I would be interested in hearing other thoughts here.
