Thought I’d visit this site again. I no longer have this problem, it was corrected surgically. Sounds drastic, but it really basically was just a tiny nick and they were able to kill the vein which was causing the problem - no side effects at all.
About the issue itself, like some others have said penis heads are meant to be softer then the shaft, that is normal. However, you will definently know if you have this problem. For me, I could not even kegel and make my head expand previously -it almost felt like it was disconnected from my dick. And it remained very small, and ‘lifeless’ when hard. Now, I can tell it is normal since it is a lot bigger, remains full and feels great - unlike before. If you start having this problem I would advise to stop PE immediately, and see if it gets better. If not, I have read some people claim that PE has improved things for them. Personally, I feel they may not have had what we have in the first place … because I know PE could never have fixed what I had. And it seems for many to cause this shit in the first place. But, everyone is different so it may have some merit - but I am very doubtful.
If the problem is a leaking vein, which is easy to isolate, the surgery I had is always a viable option to this problem. Whatever you guys do, good luck and all the best
