I've had two circumcisions, both in my teens. I grew up with a very small penis with a foreskin like a trunk which kept getting sore and tight so that it wouldn't pull back and gave a lot of trouble. My parents wouldn't do anything about it, but when my home broke up I went to a new home with my aunt and her partner, and they both liked boys to be circumcised and they wanted me to be. At first there was a snag because parental permission was officially required, and my dad wouldn't give it, but they got the doctor to say I needed immediate surgery because of the tightness and soreness and also because it was stopping my penis from growing to normal size, and so I had what was a loose circmcision in all but name which made it so that my knob was uncovered and there was no more soreness or anything, but there was still quite a lot of foreskin. After I was 16, though, parental permission was no longer required, and so they arranged for me to have the sort of circumcision they liked, which cut off all the rest of the foreskin and left my knob permanently completely bare and proud, and what was left was just the bit of skin to cover the very short shaft that I have..
I'm in the UK where there's not many circumcised guys, but I love it and I think it would be better for a lot more UK guys if they were circumcised. A lot of people talk about the advantages of it being cleaner and not so easy to get HIV and so on, but it's really more than that. With me it just made me feel grown up when I was fully circumcised and it feels nice and I'm proud of it and like showing it even though my penis is so small, and I know it's the same with a lot of guys who get cut when they're older and I think it's reasons like that why circumcision has been going for thousands of years.
