More than just Porn-Induced? Really confused/discouraged.

35 year old male. I've made it to about 100 days without any porn. Failed a few times looking at Instagram pics, but no rush of dopamine like before. M occasionally but nowhere near as frequent.

My PIED -- if it's PIED -- has not improved much.

1. I can't mentally queue an erection like in my younger days.
   
2. I haven't had any morning wood in years.
3. Making out with my girlfriend (clothed) does offer some sort of erection, but it's considerably softer than it ought to be.
   
4. Ejaculation when I do M has been weak for a very long time. I've had (unrelated) skin allergies that have caused dermatitis. The doc always prescribes prednisone to reduce the inflammation. While taking prednisone, ejaculation is easily ten times stronger when i M. No joke.
5. I suspect I have some sort of worsening depression for years now. While I don't feel sad, my range of sad-to-happy emotions is continually getting more and more "boxed" in. Let's say 1 is sad and 10 is really happy, and a healthy person experiences feelings 1 to 10 in their daily lives. My range runs from about 5 to 8. I rarely feel sad or really happy/excited about things. People compliment me for being "so mellow" and "calm and collected" under the pressure but I don't think that's a positive character trait, but rather a symptom. In short, I don't "feel" things the way I should, nor can I concentrate very well.
6. My feelings of adrenaline when driving in the car, for example, are almost non-existent these days. I can be going somewhere and another driver cuts right in front of me. Everybody else in the car gasps and their heartbeat/blood pressure goes haywire, but not me. I didn't used to be this way.
7. I was on Adderall for 17 years. A doc told me many years ago that ED was a possibility. I stopped taking Adderall earlier this year and there was no improvement.

So while I've seen benefits (less anxiety) in quitting porn, I still feel the biggest problem is still undetected. My GF and I are not having sex, and she knows about my past porn problem. I haven't told her about the ED issues. She wants us to get married (as do I) but this issue is haunting me badly. I'm afraid to put a ring on her finger without some serious improvement.

Most doctors won't listen long enough to understand these types of problems, so if you agree that I need medical help, could you explain what exactly? Should I be pressing for antidepressants, or for V-iagra, etc? Should I see a urologist as opposed to a regular doctor?

I welcome any thoughts or encouragement. Thank you.
