I have a question that is probably simple.
I can pull my foreskin all the way back, but no matter what, it will always go back over the head of my penis on its own.

When I'm erect, I'm able to pull the foreskin back, but once again, it will slip back over (and also, the foreskin sort of bunches up at the corona of my penis before going back over).

So I have two questions about this.
1 - Is it normal?
2 - How can I fix it - or can it be fixed?

Thanks in advance.
