and I'm really happy that I wasn't. IMO it should be the decision of a person to circ or not. If you want to circ at age 20, go you. At age 10 foreskin fully peeled and I was able to fold back skin completely. As long as you take shower at least once a week there is no problem in cleaness. I'm really glad that I have foreskin left. The very end of tip is slightly desensitized and I can't imagine my whole head feeling that way, then all I would feel the pleasure from would probably be from BIG pressure on side of dick and not stimulation. IMO, the tip of penis (head)doesn't have a proper skin layer to protect it from exposure, its like 1mm thickness. Foreskin is obviously there to protect the penis, even when wearing the most comfortable underwear it will become desensetized, I imagine.
Also think about it, how would you women (I think a lot of you here are) feel if the skin covering clitoris was cut off from females? You say its not the same, butit is. TIp of penis acts very much like the clitoris and overall just as sensitive (unless u desentecize it by circ). Go ahead cut off hood from clitoris and expose it to 16+ years of all kinds of fabric/jeans/whatever materials there are.. and see how sensitive it will be
