I provide the following information for statistical purposes only, since personal experience seems far more valuable to this discussion than reading an internet article.

I was circumcised when I was an infant. I do not know if it hurt or was otherwise unpleasant because I do not remember it in any way. Personally, I take that to be sign that it wasn't very painful. In contrast, my earliest memory is getting vaccination shots at about the same time. To this day I am terrified of needles.

I have never had any difficulties being circumcised nor have I, nor any of partners, ever had any complaints about my abilities. I can only speak for myself, but trust me, I have no decrease in sensitivity. I do not know much at all about health benefits, but I am personally extremely happy that I am circumcised simply for cosmetic reasons. Being happy with how you look is a very important thing and my wife and I both prefer the snipped appearance to the non-snipped.

So, as I see it, it is a procedure that is less traumatic for an infant than getting injections, plus it improves his physical appearance later in life. That's a good enough reason for me. If there are health benefits on top of it, that's even better, but even if there were not, it wouldn't change my opinion. My wife and I both agree that any son we have will be circumcised for these reasons.
