I don't think there is an answer to this. IMO, natural makes a man more in tune with his natural sexual feelings (he has some that have been CUT out of a cut man's life). Natural sensation may make natural men think about sex more. However, lusting for sex and being promiscuous are not the same thing.
To the person that had all of the misinformation...
Christians have in NO way spread circumcision. Circumcision is not part of Christian sects in any way. Mutilation, which circumcision clearly is (it is a removal of healthy erogenous tissue), is abhorrent to Western Civilization (abhorrent from the legacy of Greek and Roman empire : West -- latin based cultures and Eastern - Greek based cultures). It may be noted that the traditions of Western Civilization may well have rejected the message of Love of JC if it was also a requirement to harm your child. Western (christian) culture looks at circumcision as harm to the natural form, harm to a defenseless baby and therefore at odds with the Christian message of love your neighbor.
There is no data that shows HIV, HPV or any STD change or any real benefit in real populations as to cutting off parts of a baby boys penis -- not in the US, EU JP.... Even in Africa (with water issues) about the same number of cut men and natural penis men have HIV. Real world studies how that a man with a natural penis is at no higher risk of HIV and HPV.
As to the theory that penis parts should be cut off in order to facilitate hygiene, consider the following comments of a pediatrician. This is certainly a different (and more logical) view of Hygiene:
"My experience as a pediatrician has convinced me that circumcision makes the penis dirtier, a fact that was confirmed by a study recently published in the British Journal of Urology.1 For at least a week after circumcision, the baby is left with a large open wound that is in almost constant contact with urine and feces--hardly a hygienic advantage. Additionally, throughout life the circumcised penis is open and exposed to dirt and contaminants of all kinds. The wrinkles and folds that often form around the circumcision scar frequently harbor dirt and germs.
Thanks to the foreskin, the intact penis is protected from dirt and contamination. While this important protective function is extremely useful while the baby is in diapers, the foreskin provides protection to the glans and urinary opening for a lifetime. At all ages, the foreskin keeps the glans safe, soft, and clean.
Throughout childhood, there is no need to wash underneath the foreskin. Mothers used to be advised to retract the foreskin and wash beneath it every day. This was very bad advice indeed. When the foreskin becomes fully retractable, usually by the end of puberty, your son can retract it and rinse his glans with warm water while he is in the shower."
