ive been attempting nofap for almost a decade now, and the best piece of advice i can give you, is if you are trying to no fap you will fail.
The only thing to do is just fap to porn whenever you feel the desire to do so, and pay it no mind. dont feel bad about it, dont let it consume your throughts, dont sit there and think all day about it. literally if you feel the drive, do it, and dont think anything else of it. just move on with your day.
youll end up naturally doing it far less often. the reason you do it so much is from excessively compulsively thinking about it 24/7, letting it consume your mind, letting it take over and have control over everything. You start saying to yourself that that one thing is the cause of every single one of your problems, and that if you could just stop doing jerking off, then everything will get better and you could live a normal life.
conveniently, you never give it up. you keep fapping. it provides a nice little psychological excuse for continuing in your behavior. youve taken every mal thing in your life, tied it into one action, and by continuing the action, you thus excuse yourself from all responsibility and control.
I could go on and on, fee free to PM anyone if you want to talk more about the subject or any others
