I was circumcised as a baby and I've always been unhappy about it. The losses are measurable. Four of the five most sensitive sites on the penis are on the foreskin. The form and function of a man's genitals change for ever. Never in his lifetime will he know what sex is meant to feel like. It's a violation of one's body. They're called private parts for a reason.
As an adult, I started a restoration process as soon as I got my hands on the necessary materials. The restoration of the foreskin has physical benefits: you can't grow erogenous zones, but a functional facsimile of a foreskin is possible. Sex gets better, though it's still tinged with sadness.
I blame the medical profession. My mother just didn't know. Presumably she was told, unless you do this, he'll drop in his tracks at age 12. Back then, everything from epilepsy to club foot was said to be cured by simple removal. So many things were said to be cured by circumcision, but men who stayed intact aren't falling to the ground, clutching their crotches. I support causes that try to stop female circumcision - people call that genital mutilation. It's equally so for boys.
Thankfully, my family - my wife and two daughters - have been supportive of me, so I suppose I would say, yes, I am happy. I've certainly managed to make the cup half-full and filling, and if that's the case, I'm doing quite well. I've done the right thing. On balance, I'm a happy bunny.
