Dr. I am having a painful problem and the problem is that. When I pull my foreskin back during flaccid state. It comes back. But after that I got the erection. And my foreskin get stuck behind the glans. And the glans swells up. Preventing the foreskin to come back to its normal position and I have pain in the tip of my penis foreskin. And the glans becomes darker in colour (light greyish). So doctor what treatment is available for me. And my age is just .21. At this age can I perform the treatment that you will recommend to me.
