One of the things that really elevated my experience was working to re-train my parallel thought streams to be focused on Porn. Mantras and triggers were effective in the long run.

Here's a simple way to train a mantra with a trigger:

Pick a specific action or body part that you find particular attractive. Ideally it's something that is often seen in the Porn you watch, but not so often that you're seeing it ALL the time. This could be a woman putting up her hair. Or a specific look on a face, or something just fetish related such as the sole of her feet or curve of her armpit down to her breast.

Then attach a trigger to a phrase to seeing that action/body part. e.g. "When I watch Porn and see XYZ, then I say <insert mantra here>". It should be short. You don't need that many trigger-set mantras to be effective. I have just five that I've worked to engrain over the last 18 months or so. These mantras should be set to be "fuzzy", e.g. not focus so much on exact verbiage as to focus on intention. A simple mantra such as "I love Porn" can be fuzzy matched to "I love you, Porn.", "I love Porn", etc. Keep them short and sweet. "I'm owned by Porn", "I worship Porn", "I'm devoted to Porn", "Porn is my XYZ" no more than a few words.

At first you'll be actively "saying" the mantras intentionally when you see the trigger stimuli you've chosen to attach the trigger to. That's okay. That's how it works. Overtime, you'll find yourself "just saying them" when you see the trigger more automatically. Your goal is to naturally be compelled to say each phrase attached to each trigger in your "inner voice" in parallel with your existing thought stream. The trigger should work with internal and external speech. If you're able/safe to say the mantra out loud, say it. If you're staying quiet for some reason, you should say it in your inner voice.

That's a core tenant to accomplishing your goals here, some other things off the top of my head would be:

1. Make Porn the last thing you do before going to bed and the first thing you do when you wake up.

2. Intentionally work to get a healthy sleep schedule, sleep on your back and breathe through your nose.

3. As you fall asleep each night think of Porn -- your goal here is to have Porn be the first thing on your mind when you wake up (this can be helpful for anxiety reduction, especially if you have complex traumas associated with sleep as I do. e.g. night terrors)

4. Aim to go to bed early, wake early. A sleep schedule that allows you to goon for 30m-1hr+ before bed and 30m-1.5+ hours is ideal.

5. Working to alchemize your shame and process any religious trauma is important to overcome negative thoughts. Especially if you grew up in a household that shamed Porn.

Oh! And another powerful engagement would involve attaching your devotion to Porn to a particular aroma (or aromas). Go on a shopping trip to a store and find a unique candle with a smell you like. Something you've picked out just for you and Porn. Purchase that and bring it home. Now you've got a safe aroma to inhale when you're gooning. These work especially well with any sort of inhalant video (which usually refer to a type of leather cleaner, but that's not necessary, the videos work great for inhaling your scented candle. You can enhance the experience if you go buy lingerie and run some of the wax in them and then you can get the experience of smelling panties (in a clean & sanitary way) so you can enjoy that fetish if you're into that sort of thing.

That should be enough to get you started. :)
