@Reanimator; In America 75.75% of men are circumcised. As of 2008, 76% of Americans identified themselves as Christian.
Correlation doesn't = causation I know, it's just something to chew on though.
From you many years on earth you've figured out that most girls like it circumcised. Even though it's much more pleasurable for the man to have sexual intercourse without a circumcised penis? It's also less brutal on the woman, as uncircumcised men have a much better feeling of when they are about to ejaculate and ergo, don't pound women like dogs?
But hey, if you want to cut a bit of your penis off because from 'what you've figured out, women like it circumcised', then go ahead. It's your body.
