Ok my friend, I see you do not like the Rosary. But of the prayers it offers so much Grace it is not believable. When do you normally do it? If you say the Rosary around this time, it is almost impossible that you should fall into this sin. Indeed, the quote above is do totally true. Sin cannot abide in you if you say the Rosary.
The real struggle then is saying (I mean praying when I say this) the Rosary. The urges may feel extra strong if you do not do it. So pray it every single day without exception. it should not be long before the results come in.
Also, do mentally pray, try for every night before you go to sleep.
At the VERY FIRST INSTANT that you feel temptation, pray. Do you have a crucifix? How realistic is it? Regardless, also think of Jesus crucified in much detail.
And also, whenever you get a disordered thought to lust, strike yourself or do some other form of physical pain. Not enough to injure you or anything, just enough to feel it and get your mind off of it.
Also, make a commitment in your mind to become a saint, and pray about this.
What I don’t suggest doing is to start fasting all the time. You’ll feel like you’ve exhausted your will power quite possibly.
And yes, pornography IS an ADDICTION! There’s a website I want you to look up, yourbrainonporn. Google that. God bless.
PS: what sort of porn is it? Online? VHS tapes? Magazines? If the latter two, just throw them away. If the former, if nothing else works, then desperate times call for desparate measures. Hopefully you don’t need to go to such lengths.
My advice applies to all else who struggle with this.
