Hi. Am 28 yr Male. I had few questions relaed to my Penis... Is it must that the foreskin of the penis should slide over the head and get it back all over?? I have a very tight foreskin and it seems the opening is very small to get the head out of it. For last few weeks I tried to get the head out of my foreskin and it have started coming out but with high resistence. Once head comes out it becomes very difficult to get it back inside. Secondly When I take foreskin completely back, it actually becomes very tight on my shaft......
