I have been very concerned with this aspect of PE also, being one of the people who never had a single incidence of ED, then had an episode about 2 or 3 months into PE. It definitely needs to be addressed. Thunder has asked for volunteers, so I plan on trying to at least get a start on the ED/PE connection. Hopefully this weekend. I don’t really know how yet. My own thoughts, subject to change without warning, is that it is likely a combination of both physical and psychological. I think by forcing the blood around via jelqing, or just the stress of growing via jelqing or stretching or hanging (although in my mind I don’t associate it with hanging, just jelqing and stretching. One of the things that need to be established) that perhaps the penis get’s to a point where it just needs to “rest”, or recover, or whatever. Maybe it’s just the shock of being worked for the first time in it’s life. Maybe there’s a lag time before your body compensates for the extra size by pumping extra blood through it. So, being in that state, one day it just doesn’t perform. It takes a break. A purely physical thing. Just like teenagers start sleeping all the time when they’re going through a growth spurt. Sometimes your body just needs rest, and will take it whether you want to or not. I think it is probably a temporary thing. But - when it comes to good ole Willy, even ONE episode of non-functioning, limp penis is enough to stick in your mind for good. So then the next time, even if it has recovered, you’re so damn worried that you won’t get it up, that BINGO, a self-fulfilling prophecy - no erection for you! I think from that point on it becomes psychological. Classic Performance Anxiety. It is very, very, very hard not to think (worry) about if you’ll lose your erection, once it’s happened before. A vicious cycle. Or else, it’s due to just being so focused and aware of your size (or perceived lack of - let’s face it, there’s not a man here who is deep down content with his penis size, whether he starts with 4” or 9”, or else he wouldn’t BE here), that you let the genie out of the bottle, so to speak. Feelings of doubt and inadequacy. Although I am very convinced it starts as a physical reaction to PE. What triggers it in some men and not in others is a subject of great interest and study.
