Circumcision is suspected by many to actually lead to
desensitization the
glans (
head of the
penis), as this part of the
body was not designed to be constantly
rubbing against
clothing. In theory, the
incessant stimulation of the
members of
circumsized males will reduce the
sensitivity—thus making
sexual activities less
pleasurable. Unfortunately, I haven't heard of an actual
study of this
phenomenon.
Infancy is exactly when one does not want to be subjected to the sort of painful trauma experienced during circumcision. Having parts of one's genitals chopped off is traumatic at any age.
Circumcision is not necessary for cleanliness. The uncircumcized penis can be easily kept clean: a simple 15-second rinsing every time one showers is an effective and simple method of ensuring sanitation and well-being.
While it is certainly nowhere near as severe as female genital mutilation, it is still no simple medical procedure. It's a bizarre, barbaric, and completely unnecessary practice.
