I am trying to wrap my head around the hangover issue, and will admit that in life I am a dopamine chaser.
What I have been teaching as an erotic practice to my clients is the non-negotiable activation of the parasympathetic nervous system via bonding behaviours and intentional trance state (means extremely relaxed physically and mentally) and being 100% present in the body, then attention and awareness of the sensation. This in itself is very bonding in my opinion.
Where I believe there is conflict is that in that wonderful state is where much intensity can be experienced, for example I feel far more extreme pleasure in that state where there is not very much physical activity and no efforting than I ever did when I used to engage in wild crazy breeding sex. I happen to be extremely physically responsive and very easily orgasmic, so our play focuses more on preventing me from orgasming so that I can feel higher degrees of pleasure than if I were simply to release the arousal relatively quickly. My partner naturally does not ejaculate often so that is not an issue.
I also move energy away from my clitoris and up into my body, actually I prefer internal and breast stimulation to clitoral anyway.
My question is are the highs of pleasure in these circumstances damaging from a Karezza perspective? Taking any orgasm out of it, is the intensity (which admittedly we both love) itself detrimental? Is it just the dopamine train that has me clinging to the intense sensation and arousal? Again, this is all done from essentially a relaxed trance state where we have cuddled, relaxed, let go and began from there.
Love to hear perspectives!
