After reading most of this thread, I wonder why it is that you are so adamant that your problem is strictly physical and not related to some anxiety related issues. Our mind is powerful, especially when it comes to it’s affect on our penises and how well they function. You may have indeed injured your penis using a pump, but it seems rather unlikely considering the amount of pressure you were using.
That lump you mentioned that went away or flattened out, is not something one should ignore. What did your urologists say about it? I had a bump just under the head of my penis years ago which I thought was a pimple or a cyst. It was surgically removed and although it was benign, it was deemed pre-cancer….whatever that actually means. It never came back. Being a proactive guy like yourself, you definitely need to have this checked out.
Believe it or not, you just obsessing about your penis function can be causing you some of the difficulties you’ve mentioned. Please don’t discount this. It might be an easier fix than if it is actually something physical.
I had prostate cancer a couple of years ago. I elected to have a robotic prostatectomy. My doctor warned me that there could be problems with erectile dysfunction and that my penis would be shorter. He was right about both things. My prostate was the size of a racket ball. When it was removed, so was that portion of the urethra which ended up shortening my penis by about an inch. I already suffered erectile dysfunction and the prostatectomy didn’t make it any better. The good news is that I still have feeling in my penis and when I orgasm, it is sometimes more intense than before, despite that there is no ejaculate.
I can get a rock hard erection if I inject enough Tri-mix. The prescription calls for me to use this once a day. I’d go broke if I did this. According to my urologist, erections are essential to penis health, whether artificially induced or not. Like with you, oral erectile dysfunction medications have no positive effect on my getting an erection. I use a pump because the erection I get from this is actually more pleasurable then the injections which can cause a painful erection. I am also seeing some growth. I use a pump with a gauge and have pumped higher than you mentioned with no negative results. I suspect each of us can handle different amounts of pressure within reason. I am a person who goes at things slowly and with caution.
After dealing with erectile dysfunction for a couple of years, I have come to the conclusion that at least a portion of my problem is mental. When you live with something long enough, it becomes a routine. I’m currently considering hypnosis to see if I can teach myself to bypass my history and fears of failure in hopes that it will produce a positive change.
If you truly want to fix whatever is the problem with your erections, I believe you should be open to all possibilities and not limit yourself by believing that it has to be physically caused. What if you are wrong? Think of all the good times you’ve already missed. I say give the mental thing a shot. What have you got to lose?
