How serious is my case? Hoping to get some advice as I'm freaking out right about now

I'm not sure if other people share my fear but my main concerns are

1) I hope it's not a serious medical issue and
2) If it's not medical, I hope it's not permanent and irreversible

I'm going this weekend to the doctor for a health checkup just to rule out any medical issues.

I just spent all day reading about PIED and now realize this sounds like me. I knew things weren't going in the right direction but I didn't realize it was as bad as they are now.

Here's a quick summary:
- I've always had performance issues during sex (finishing too quickly) so I turned to porn to help me last longer but not being as horny when I finally do have sex
- Over the years I realize that turned into an addiction to the point where I now basically watch porn as a hobby.
- I can get an erection while watching porn but it takes longer and only after I start masturbating and forcing it (whereas before just opening up a porn site used to give me an erection)
- For a very long time now, I've had issues where I lose an erection during sex while wearing a condom
- Things have progressively gotten worse and now I'm having issues having sex most of the time. I still manage to get hard during a blow job (although not as easily as I should) but as soon as I try having sex, I go flacid. If I go a few days without porn/masturbating and have sex, I can usually get hard (I think) and have sex (because by then I'm very horny) although I will likely cum very quickly or possibly lose my erection quickly
- Overall I just have a hard time getting and maintaining an erection during sex now

So for obvious reasons I'm freaking out right now. If it's purely PEID and giving up porn and fapping is going to reverse my situation, then I can deal with that.
