This might seem strange, (but Neoma Isadora said it already) but while using the porn, you could - and should - use the sexual orgasm energies in workings and meditations. You could also use them to help you reduce or stop your porn addiction, if it is an addiction.
You could use your sexual orgasm energies to programme your Mind and Soul to reduce your "need" for porn, or reject it. Due to the amount of time you have spent looking at and enjoying porn, it might not be very easy at all, because each orgasm is powerful and creates things deeper and deeper; but if you use the affirmations to reduce your "need" for porn, or to reject it - and don't keep on thinking after your workings about reducing/rejecting porn - then sooner or later it should start to be easier.
An example affirmation could be, "This sexual orgasm energy is reducing my desire to masturbate over porn in a safe and positive way." You could say to reject, rather than reduce, of course, and you should make your affirmations your own, as they work for you. You could do this affirmation each and every time you orgasm - multiple times per day, perhaps; or if you do orgasm quite often, then a couple or a few times per day doing this, and the rest of the times could be used in workings for other things, such as building up your imagination so you can use that to create scenarios as you please, instead of being forced to see what you are told to see in a video or picture.
You might not want to go too far - I would start with reducing, then go on to rejecting later, but I am not you, and you no doubt work differently. Change takes time for us at the moment, and things have to be possible physically - it won't change overnight, unless you end up in a coma, for example. Also try not to expect anything; expecting and setting a date and time as to when it will happen will, more likely than not, lead to disappointment and frustration - keep a clear head.
Key points:
After orgasming (or before, if you prefer), repeat the affirmations 8 times for eternity/forever, or 9 times for permanence in terms of ending something (your addiction/reliance on porn).
Don't keep on thinking if the working is working or has worked yet; let it be.
You can use your next 1, 2, 3 (for example) orgasm times to boost up this.
Do it every single day without interruption and without forgetting. If you do miss a day, don't be disheartened; just continue.
You should be consistent - like doing the working every day, the same number of times each day should also not fluctuate - if you masturbate different amounts on different days, then just still do the workings at least once or twice per day, for example.
You can add SATANAS before and/or after the affirmations.
You can add AUM at the beginning and/or end.
You are you, so you might need to practice with these things to fine-tune them for you specifically; what I have typed might be only 80% helpful; I don't know your life so you need to make it 100% correct for yourself.
By the way - you should also be dedicated, if you are not yet. You can then ask Satan for help with your problem - but now you have shared it, that is getting rid of a bit of it, which is good!
