you guys are forgetting the original purpose of circumcision was the religious belief that pleasure=bad. Most religions cut the foreskin off to make sex less pleasurable. Therefore, it makes sense that you would have less sensetivity after losing your foreskin. Your foreskin is not a neccessary part of your body, however it does have many neural receptors in it which allow for more pleasurable feelings with sexual experiences. Despite the losing feeling you may never miss if you have it done as a child, circumcision is a perfectly fine and healthy.
