Ok so my tips are (worked for me maybe not for you)

Don't feel like you loose if you watch porn even if you don't fap, everytime you watch porn but don't fap you'll have a double satisfaction, it's a success. The dangerous thing is that when you watch you want to fap.

If you suddenly try not to watch porn at all, block websites etc. you'll feel frustrated, then you'll want to watch and fap harder and after you'll feel like a coward. (it's like you are very hungry) Don't do this.

The thing to understand is you watch porn because your body and your brain want it, when you watch porn AND fap your body and your brain are (temporarly) satisfied.
With time (if you don't fap), your body and brain will find porn useless because you will not masturbate so no satisfaction for them, they will not ask you to watch porn, they'll find another way to get what they want.
