Interesting topic in a gyne forum.
Irish lad, I assume you're in Ireland. It's interesting that Europeans and Americans treat circumcision in an entirely different way. It's pretty much the norm in the US, but most Europeans don't get circumcised. I have a buddy from London who swears that it's a huge mistake to get circumcised, because of the decrease in sensitivity of the glans. I'm a doc, but not a urologist, so I don't see this in my practice. But it stands to reason that epithelium (skin) that's almost always covered (by foreskin) will be more sensitive when exposed to the elements
than skin that's always exposed.
Regarding circumcision as an adult, my dad was circumcised while in the navy. He had the same problem you did, and he was encouraged to get the procedure. It went well, but the swelling with this kind of surgery is intense, and he said he was quite popular with the nurses on the ward as he recovered.
Anyway, if your doc thinks you need it, better take care of it. And here's a thought: Although penile cancer is rare, it does occur. It's almost unheard of, though, in circumcised penises; almost all cases are in uncircumcised penises.
Good luck!
