Good luck man! We are all on this journey together
Is it possible to ever be fully healed?
Honestly for a severe decades long addiction like mine, I'm not sure
But I have noticed significant improvements when I had long streaks in the past (longest was 8-9 months)
It seems most men report the same, so I am confident it does work
Plus even putting PIED, etc. aside, focusing our efforts on productive things inside of jerking off to T&A on a screen alone will make us better men
So I think ending this compulsive behavior is definitely worth the struggle
I am not sure if it is pied or venous leak.
Regarding this part, can you get an erection to porn?
Do you get morning wood/nocturnal erections?
Can you get an erection to touch alone (no porn)?
Can you get an erection with a partner?
If the answer to number 1 and/or 2 is yes but 3 and/or 4 is no, then probably it is not a physical issue
But if you never (or very rarely) are able to get an erection (including to porn), then I think it is worth seeing a doctor to check for any physical issues
Hope this helps - good luck in your journey brother!
