This is going to be long reply but pls bear with me till the end
It looks like it's too much stress/anxiety/confusion/worrying...Also it may be that you are masturbating but feeling guilty of masturbation that takes away the focus of enjoying the act...and the pleasure becomes pain...
Medication: I found so much improvement after taking the milk of banyan tree POWDER FORM 1/2 SPOON (LIQUID 10-15 drops) every day in the early morning with sugar...but the relapse set me back....search on google banyan tree milk, badh ka doodh, bargad...before the medication whenever i eat red meat i got nightfall/wet dream...after one week of medication i stopped getting nightfall, and in one my relapse when i masturbated i enjoyed the masturbation for 10-15 minutes then forcefully need to ejaculate but the continuous jerking off set me back again...this milk also found in powder form which i bought for Rs. 20 only
In my case i also feel i was better before reboot than now...I admitting the fact that before reboot i came withing 5 min but i was enjoying the act...but after starting reboot i associated sexual pleasure with pain...now whenever i think of sex i fear, feeling guilt instead of enjoying masturbation...and the last thing is now i am also not getting the any pleasure watching porn...And in guilt i can't enjoy the porn/mast. but addiction triggers to still do it which results in masturbating to death grip, which caused my penis to bent and a nerve is clearing appearing on top of my penis..
I am confused and fearing....
And FYI i was successfully stayed away from porn for almost 1.5 yrs then after that started to relapse in months.
BUT PORN IS STILL HARMFUL...I am still fighting with this anti human behavior...IN MY CASE IT IS JUST THE PROCESS OF WORRY/STRESS/ANXIETY THAT TAUGHT MY BRAIN TO FEEL PAIN INSTEAD OF PLEASURE.....PORN IS DISGUSTING AND IT MORE DANGEROUS WHEN ACCOMPANIED WITH MASTURBATION...AND THE FACT NO ONE CAN STOP MASTURBATION AFTER WATCHING THIS FILTH...
