Thanks for the info Carla.

I've also read that circumcision desensitizes the penis, which means it takes longer for an uncircumcised man to ejaculate. The foreskin protects the penis like the clitoral hood does the clitoris in a woman.

Also, the foreskin is erogenous, which means that it is very sensitive and pleasurable to the touch. The "gliding" over action increases sexual pleasure for the man, one of the reasons circumcision was believed to help avoid masturbation. The foreskin also plays a function in sexual intercourse.
