That is a very practical viewpoint, thats its not worth worrying about, and I agree. I was circumsiced and I dont really think about it and I dont care. But its not really a great justification, its like telling someone born with bad knees that theyve never ran before so dont know what theyre missing out on so theres no point being upset. I dont reallt see the logic in saying no sensation is a awful mistake but reduced sensation is not a mistake at all, its a scale, if no sensation is bad reduced sensation is at least half bad.

If a child is blinded as an infant, they won't know the difference as an adult -- until they learn that their eyes were once full of sensitive nerves. How does this inform the ethics of blinding infants?

Circumcision is a form of genital mutilation. Societies have done it in the past and present. Many societies have outlawed or otherwise restricted female gential mutilation, why can the same not be done for males in the same Developed world?

Those are decisions for you to make for yourself when you're an adult instead of having it forced upon you as an infant.

An intriguing speculation. Might possibly be tested by a survey for correlation between circumcision status and premature ejaculation, though screening out confounders could pose a challenge.
