The foreskin is an evolutionary relic, like wisdom teeth and the appendix. It serves no useful purpose except to give deranged zealots something to obsess over.
The foreskin is indeed like a skin overcoat you can't get rid of and is a great repository for many diseases (like cancer for instance
Penis Cancer Causes, Signs, Symptoms & Treatment) if not scrupulously scrubbed on a regular basis and not even then in many cases.
Hmmm....would I rather have a bothersome, useless, ridiculous looking flap of skin hanging over the end of my penis or the likelihood of penile cancer hovering over my head the rest of my life?
What a "tough" decision.
As for the statistics about the number of doctors that do not use anesthesia it is unsourced and therefore not reliable and anecdotal. And even if true (IF) the trade off between the temporary pain of circumcision without pain killer and the very real chance of cancer as a direct result of this useless funny looking skin hat is a very good deal indeed.
