What should I do?

It's up to you. You are free to think of whatever, only you can choose what is allowed inside your head.

 

Its good that you fantasize about her and not other women . But try and clear your mind, focus on other things too! Be stronger.

 

I think staying with just no PM is fine. I had a similar experience when I was dating in high school. We would meet and make out but never have sex so after being with her I would go home and masturbate. At the time I didnt realize is but that was the cause of my ED and it also reinforced my behavior for years to chase real life experiences with watching porn. My advice as to why its important to give up porn, especially when you are doing it right after something real, is all the real life pleasure gets attributed to porn instead. What makes you start to be numb to real life sexual encounters (or at least for me) is that whenever you get close you finish the deed with porn, so in essence you are making it so you are only really being pleased by porn. I think you're on the right track though, taking the initiative to do it and being aware of your urges. Just remember that the fact that you feel this "hunger" shows that you either have a problem or are developing a problem with porn, so why this "hunger" can cause anxiety and push you to relapse, try to turn this urge into a reminder of how serious your problem is and how important it is to get better
