I understand your frustration.
I think you should focus on getting it into the best health possible and do no PE for now at all.
The way you describe how you got your injurys makes no sense if there is no underlying problem. Probably prone to inflammation. There are people who are constantly inflammed cause of food problems like gluten etc. or stress…
I cant see how one can get a serious injury in the tendons from 45 seconds at 1 hg, or masturbating, which then leads to severe ED for weeks. If there is no specific moment where you feel a pain due to force then you probably didnt cut or heavily injured something.
Must be an overreaction of inflammation. Take antinflammatorys.
Do you exercise your body and how does it react to that ?
We also have, mostly younger people, who cant take the subjective soreness of it and panic tense up and worry thus resulting in ED.
But once again 1 minute of 1 hg pumping is very unusual to create any reaction at all…
Pelvic floor ends at the base of the penis with IC and BC muscles.
If its tense it can create inflammation which exaberates with pulling or overusing the pelvic floor. So is it tense or is it not tense?
