I agree with NP97 and Pegasus that severe PE-induced permanent injuries are rare. Lesser injuries like superficial thrombosed veins and discoloration (often permanent) are not.
I have read enough accounts from individuals who claim to have developed penile insensitivity, venous leak, the "hard flaccid" syndrome, and the "soft glans" syndrome to come to the conclusion that at least some of them must be factual and not fabricated, however. One problem is that erectile dysfunction is relatively common, and is far from rare even in younger men. It is often hard to know if ED that develops while practicing PE is actually caused by PE, or coincident to it.
I do believe that some individuals probably have developed severe erectile dysfunction or diminished penile sensitivity as a result of PE but I think this is a very uncommon event. I strongly suspect that many of the injury reports have been fabricated for the purpose of stirring up sh*t, and Lost in Torture's tendency to repeatedly become extremely caustic to anyone who tried to offer helpful advice leads me to believe that he probably was one of those individuals, i.e, a troll.
He makes the point that PE is dangerous because some individuals have sustained permanent injury through it. I suppose that could be considered a valid point. Many thousands of individuals have died or been maimed in automobile accidents, so automobiles could be considered extraordinarily dangerous, yet most of us get in one every day, or nearly every day. Penile fracture is a known potential complication of sexual intercourse, and can result in severe ED even if promptly treated. So by the same token, having sex could be considered a dangerous endeavor.
I think it is prudent for anyone considering PE to peruse the injury/ED subforums on this, and other PE forums first, and make their own assessment of the potential risk.
There is no question that you can injure your body exercising. Look at jogging. There are many different types of use related injuries and PE is no different. Physicians say that patient history is 90% of the diagnosis. If you look at the history provided by LIT, it ranged from doing it for a year and bruising my penis to "I was barely doing the newbie routine. " As an initial matter, penile injuries are enormously common. Anybody who has ever worked in an ER can tell you tons of stories about the creative ways people injure their unit. ED is extremely common. Desensitization due to OCD related behaviors and porn/masturbation addiction is very common. Fortunately. permanent injuries are very rare--even in situations where it has been almost totally severed. Generally, penile injuries are a class of injuries where it is extremely difficult to get an accurate history because of embarrassment and a whole host of reasons, both cultural and moral. But if the patient can't or won't give the physician an accurate history, diagnosis becomes very problematic; and etiology becomes almost impossible.
There is what I call the "reefer madness" syndrome to a lot of these stories. Until scientists and society had a better understanding of the effects of marijuana, the anecdotal medical complaints and injuries attributed to a single toke of a joint were widespread and very misleading. They had the theme: "My life was wonderful and everything went to crap after I had that single hit on that joint." And society (and the medical establishment) reinforced these stories in an effort to keep people from trying "drugs." LIT's story seemed to have a lot of those elements.
