@Don Quixote I was a child of the 80s so thankfully high speed internet porn was not available during my formative years. Actually I started masturbating at the age of four (probably earlier but that's as far back as I remember) as a coping mechanism due to growing up in an abusive household. It was a pure dopamine rush, this was before I even knew what sex was. I was addicted to prone masturbation and then a sex addict as an adult although oddly I never got hooked on porn. I would watch it for sure but I never had the compulsion to watch it. As stated earlier I attribute it to the fact that it was unavailable to me as a child so I grew up without it. I'm still not 100% sure what edging means. Every time I jerked off or had sex I would certainly try to delay orgasm as long as possible. But I never jerked purposefully to try to get near the point of no return and then stop only to repeat the process over and over. Amazingly I was still able to function sexually without problems up to the point when I quit drinking. I should point out that quitting cold turkey nearly killed me, this is how bad of an alcoholic I was while active in addiction. First I went through a good two weeks of withdrawal where I would be lucid in between horrible hallucinations and wonder if this was how I was going to die. After I had passed through the storm I was too weak and shellshocked to do much of anything. Quitting cold turkey was the first time in my life that I had taken a break from masturbation for a length of time and I had started flatline for the first time back then. At some point I noticed my dick wasn't working and feverishly burned through a ton of cash going to massage parlors and barely even getting hard, if I was able to get hard at all. This was when I connected the dots and started looking online for answers. As for your questions as it relates to brain function I must admit I've never given it that much thought. I'll try to explain as best as I can. The overarching symptom during PAWS was a specific type of headache which I call the dopamine headache. It is something I have only felt while going two rounds with PAWS. The way I describe it is that it feels like there is acid slowly eating away at whichever part of my brain is affected on a particular day. Sometimes it's a sharp pain through the top of the crown, other times a dull ache behind the eyes, sometimes a vicelike pressure on the third eye, sometimes left hemisphere, sometimes right hemisphere, sometimes the base, etc. I don't know if there is a correlation between subsequent symptoms and the particular part of the brain is aching (should have kept a detailed journal). But my theory is that whatever symptoms I would have on a particular day would be directly caused by the part of the brain that was aching. A big one was fatigue but it wasn't the type of fatigue one would normally have. My body itself never felt tired or restless. Rather at some point in the early afternoon my brain would start to shut down. Having covid as a cover during this whole ordeal helped me big time. While "working from home" I would have lunch and soon after hit the bed once I felt my brain shutting down. I'd wake up two or three hours later feeling completely drained as if I had just had the most intense physical workout ever. The easiest way to describe the effects of brain fog were my attempts at reading. I'd try to read something and it was almost like the words themselves were blurry. This wasn't an eyesight issue (although some days my eyes did have problems). My eyes could read the words legibly but my brain was registering them as being blurry. Which was a moot point anyways because I could only retain two sentences in my short term memory at a time. Therefore reading was pretty much a lost cause on days where I had brain fog. Thankfully I didn't suffer from anxiety/depression during this round of PAWS. Some days I was a little down but that is it. When I got sober from alcohol I was damn near suicidal until month 21 when it all passed. It's funny how I exited PAWS this time at month 20. For some reason this is how long my body seems to need. Both times I could tell beyond a shadow of a doubt that it was over, it was that sudden for me. If I were to describe the difference between how my brain feels structurally between then and now the best word I could come up with is that my brain feels calibrated again. Before the dopamine headaches would throw off the center of my brain's internal compass and it didn't feel like thoughts were passing through correctly. Now the headaches are gone, I've recalibrated, and thoughts are passing through my brain like clockwork. My brain feels CLEAN. Regarding your comment about the "thinking nubs" I can't really compare because I never put too much thought into this stuff before I dealt with PAWS. But I will say that when I meditate I can feel a tendril connecting from the backs of my eyes directly to my third eye. With certainty I can tell you that this is something I've never experienced before. I tried to type this out as fast I could so hopefully it's not too scatterbrained. Thank you for all of the contributions you have made to this community and I hope you recover quickly from covid.
