Delete it, and show yourself that you want to change. Are you saving it for an epic relapse in the future? What purpose does it serve at the current moment?
Delete all porn content and start reboot. If the brain once worked well before porn, then after the healing process it should be like old good times before this shit. I am in a similar situation myself, I started the fight and I want to continue it , until the victory over this damned gutter. The most important thing is a good beginning and a strong resolution to improve the life messed up by the bad things. Some time later it will be easier to go on a new path. Greetings!
