I have realized that I have been having this problem for quite some time already. My foreskin cannot be fully retracted. If possible,can I can post some links with spoilers showing exactly how my foreskin looks like? I found 2 pics on a safe website which looks almost like mine when it's flaccid,and when I try to pull back. Is it necessary for me to circumcise? I'm 19 already,and wondering if I'm too old for it. I prefer not to though,as I heard circumcision has it's cons. How can I fix this problem? I scared that next time it would be pain when having intercourse. Imagine the friction moving my foreskin up and down when even now it can't even go down. I heard that stretching can help,but I don't really know how to do it. Just for more info, when my penis is flaccid,I can retract the foreskin until a string prevents me from further retracting it,but when my penis is hard,it's harder to retract and I can only see a little bit of the top part of the head...
