About a year ago, I was doing clamping. Basically, I wait for an erection and then clamp the base of the penis with this thing to create pressure and increase girth over time. The problem is that, besides the advice, I kept the clamp for long periods of time, sometimes even 20 minutes. I frequently ended up getting this sore feeling that you feel when blood get stuck somewhere in your body. I did it inconsistently for 3 months and stopped since then. I also did and I'm still doing penis hanging for length. I hang weights to my penis with a vacuum device that attaches to it. Ever since I started all this journey with clamping and hanging, I noticed a decrease in my erection quality. In particular, I don't get morning wood as hard and as often as before. The situation hadn't gone better even when I tried taking long breaks from this penis extending journey. I should also mention that I masturbate often, almost every day. I have some problems quitting it. Did I destroy my penis permanently? If so, could this decrease in erection quality be cured/treated?
