Manual Stretching has permanently F’d me up 11 months ago with no recovery in sight. My shaft is less than 50% of how it used to feel. I don’t get any morning wood, or spontaneous erections. I did a light stretch about 5-7 days ago, and now my glans is at about 50% (it was about 100% before then, despite my shaft being rubbery for the 11 months). Something is not to be messed with in there guys (at least for some of us). Now my d1ck is less-reliable, less-responsive (requiring more physical manipulation and stronger mental stimulation), and about 50% as sensitive as it once was.
This problem is real guys.
And it sucks being where I am now just because of some very firm/controlled manual stretching.
