Why when boys arent cirumsized they have excess skin on their penis?

Answer 1

That skin is definitely not excess! It's very important to a man's sensitivity and to his woman's sexual pleasure.

A new study proves conclusively, beyond a shadow of a doubt, that circumcision decreases sensitivity for the man. http://www.blackwell-synergy.com/doi/abs/10.1111/j.1464-410X.2006.06685.x

A full 90% of women say sex is better with an intact man. http://www.healthcentral.com/drdean/408/60750.html

An intact man is just as clean as a cut one. If he washes his penis, it's clean, cut or intact. If he doesn't wash it, it's dirty, cut or intact.

Answer 2

It's not excess skin. It's an integral part of a normal penis and cutting it off is like cutting off a woman's vaginal lips. Circumcision removes over half the skin of the penis (about 15 square inches in an adult) and it's not just simple skin. It's packed with nerve endings, special anatomical features like the ridged band and has a unique elastic gliding action, allowing it to slide on itself and act like lube. This action is what most males use to masturbate with except those who are cut so tightly that they have to use lube or just rub it dry. Of course the intact male has the option to use lube too if he wants to. During intercourse it acts like lube on entry and may act as a dam, preventing lubricating secretions escaping from the vagina. In one study women reported that sex with an intact partner was gentler and more satisfying since he doesn't have to thrust as hard to feel enough stimulation. Removing the foreskin turns the surface of the glans from an inner mucosal membrane to outside skin. Newly circumcised adults usually go through some weeks of intense discomfort as the glans is constantly exposed to rubbing on clothing, until it develops a thicker keratin layer and becomes less sensitive. A new study has shown real differences in fine touch sensitivity between circumcised and intact penises and that the most sensitive parts of the intact penis are those that would be removed by circumcision.

Answer 3

Uncircumcised boys don't have excess skin on their penis. That skin is called the foreskin, and all males are born with one. Circumcision is the removal of that skin. It is done for mainly cultural reasons, but in rare cases is medically needed.

See links for more info, some of the info is clearly biased against circumcision but it has good data nonetheless.
