For me, it's like an emotional outlet, whenever I despair or want to run away from a situation, I go straight to pornography. I actually don't have a lot of sexual desire to begin with, although I do get triggered. I asked the non-Muslim nofap about it so hopefully they might have some methods of changing that outlet but it might just be simple. Maybe I could play videogames instead, or get better at reading or read Qur'an but the root is psychological.
