I remember fapping so many times a day that I'll get a kidney pain. I also have weak adrenals and was prescribed cortisol. On my NoFap streaks I have more energy and feel alive. How does excessive orgasm affect the kidneys and the adrenals? If I have weak adrenals does that mean that normal sex is also to be avoided?
I dintend think there are any studies but I do believe that overstimulation of the adrenals... be it through sugar, alcohol, drugs, masterbation, overtraining/exercise, lack of sleep and so on does create an issue of burnout. This is just my opinion. I know all of those things minus masterbation and exercise are damaging to insulin sensitivity/functioning that is a big part of a lot of what's going on.
