Well I'm 29 years now and have had a tight and quite long foreskin(a little more than half an inch)Only of recently I started the stretching exercise and as of now I am able to pull back the foreskin when flaccid.I recently visited a urologist to ask if I require circumcision. He said no and also told me that no one can pull back the foreskin when erect.But as I have been reading up, the foreskin is supposed to go back enough for the penis head to be completely visible which isn't the case with me.Here's the deal.I am able to pull back the foreskin when flaccid but not completely back as the foreskin gets clumped and stuck and my penis head bends. Then it becomes a little difficult for me to get the foreskin back to normal. I have to use both thumbs and index fingers to push it back to normal.Also if I try to pull back the foreskin when erect, it hurts a lot.I am confused as to why is this happening.Do I need to continue doing the stretching exercises especially when erect?OR I should stop because I have a short frenulum it will keep hurting and probably the frenulum will tear?I went through the thread in the archive which was started by lance. And what I have understood is that even the frenulum can stretch like the foreskin over time.What should I do?
