So should I cool it off with some light workouts until conditions improve? Or is my workout not that hard, and I should just drop the intensity of my grip?
I do not know enough about mechanical PE to advise you on the effects of your regimen, or changes you ought to make to it in order to regain erection power. About mechanical PE, I have lots to learn, nearly from the beginning; others here may probably advise you better on it’s variables’ effects on erection. Some in the forum indicate that PE has greatly improved their erections, while others indicate that PE has diminished their erection power. I do not know enough about such PE to explain within PE particulars those erectile differences in results. The Physiologic Indicators, given in an earlier post in this thread, looked useful, though.
I figure that the main difference in erectile results is the question whether jelqing, on one hand, is infusing expanded but sound penile tissues with a greater supply of blood, or whether jelqing, on the other hand, is weakening tissues, causing leakage, or toughening tissues as through scarring. That schema might not be exactly correct, but that is my approximation, what I figure, of the key difference between erectile results.
Based on that, I figure that to restore or improve erection power, one either would reduce the mechanical PE, so that the penile tissues are less physically stressed, or would improve the quality of the penile tissues to handled the applied physical stress. For instance, I believe that low testosterone causes atrophy and increased fibrosis of penile tissues. I believe that low blood oxygen, as from smoking and shallow breathing, causes increased fibrosis of the penile tissues. I believe that imbalances of fatty acids can tip tissue response toward inflammation and damage. I believe that low thyroid-hormone function lowers both circulation and tissue integrity, including blood-vessel quality.
I do not know enough about mechanical-PE dynamics to advise you on changes to your PE routine itself. The indications that I try to make here concern overall male and penis health, regardless of PE routine, with or without PE. Erectile power flows mainly from internal dynamics. If you have specific questions, set in practical context, more from this perspective, I could further discuss particular of my relevant understandings. Or maybe I could direct you to information.
