Doc, I am 22 yrs old. I have this foreskin over my penis. I haven't gone through any kind of Circumcision. It hurts very well to keep the foreskin behind the penis head for long time. And even if I ignore that and do sex, Its difficult to get the proper orgasm and dick may lose erection at times if i lose concentration, and at the end of the day, i will get a swelling beneath the penis head and cannot pull back my skin for the next two or three days. Tell you what, I am damn worried. I am planning for a circumcision even, since my friend advised me to. I am afraid.
