The foreskin is the most erogenous part of the intact penis, cutting it off is going to reduce sexual pleasure you brain dead monkeys. Of course the medical establishment is going to say that it doesn't- they make billions of dollars a year off of this scam and they have a vested interest in promoting the idea that somehow or another genital cutting is beneficial.
The argument of enjoyment is debated (even thought a support it there has not been a serious study about this) but its easy to see how circumcision damages sexual functionality, circumcised men need lubricant to perform sexual acts (masturbation and coitus) which is not normal. Uncircumcised men do no need lubricant and no animal needs it so its a clear signal that circumcision does damage sexual functionality.
Hey, did you know Israel has the lowest penile cancer rates? Hey, I wonder why? OH WAIT. Its circumcision. I feel bad for any man who isn't circumcised. Men with a filthy foreskin are always caring some kind of gross disease. Honestly, that gross thing has piss, smegma, and all other kinds of awful things in there, even if you wash, it still gets dirty fast, and still has an awful smell. Really, what girl wants to suck off a gross, ugly, dirty, anteater penis?
The purpose of circumcision of males is to increase the ease of personal hygiene, decrease the frequency of urinary tract infections, decrease risk of sexually transmitted diseases, prevent other penile problems, and reduce the risk of cancer in both the male and their sexual partners. (http://www.Mayoclinic.Org/tests-procedures/circumcision/basics/why-its-done/prc-20013585) The Mayo Clinic has not found any enhancement or detraction from sexual pleasure for men or their partners due to circumcision.
