You have to do it as a japanese man said "with the nature instead of against the nature"
It isn't a suppression of your natural sexuality/urges but rather a release of it. Think of the man comfortably lazing around with a good book rather than the kid teen strapped to a cross to stop himself from fapping.
Stop focussing so much on wymyn and stop looking at things that are going to give you a bonor if you don't want a bonor.
Don't do things hat encourage it like going to /monster/ even if it's "not for the porn" as well avoid the "totally not porn" stuff. Youll find it's easy to nofap if you're doing something like camping because you're unplugged from all the artificial overtime sexual stimulation from commmercials, pron and more.
Youll find your natural life without porn will dry up without the artificial stimulus. Your body is only supposed to be activated in this way when a woman says "give it to me baby"
Think of it like hating normies but you wanted to be successful and sociable like them. Suppressing your hate will never work and will eventually cause it to show somewhere somehow. Being able to release your hate however means you can be sociable and be happy and fine forever.
