Maintaining erection for longer periods after reboot

Hi, I'm new here and as many others i only recently disocovered i suffer from PIED.

For the last couple of years i have pretty much stopped using my imagination and have been watching only porn to masturbate and did not have sex, now i am rebooting after realizing i have lost sensitivity while attempting to have sex recently.

THE MAIN REASON WHY I MADE THIS THREAD IS:
I was able to maintain my erections for hours on end while having sex (1-2 hours on average, even longer if i tried really hard and the sex was good), does this ability come back?
I want to know from people who had the same issue and rebooted, does this ability go back to normal? Does the reboot take much longer in order for this to be achieved?

Can someone who has been through this give some feedback?

Share your experiences with me please, this is/was my "wow" effect on women and my "pride" and I started battling mild depression once i realized i underperform due to dopamine receptors being desensitized and my penis losing sensitivity due to constant death gripping, I just hope it's not too late to recover.

Thank you for your feedback, cheers and beers
