Circumcision is obligatory for all Muslim men and as far as I know, it is even practicsed by Jews and Christians. I remember in one episode of Sex and the city, Charlotte (who happens to be an Epascoplain Christian character)who got really taken aback when she found out one guy was not circumcised and she discussed with her girl friends and they all advised her to go ahead. Some of them said they have had experience with non-circumcised men.. So from what I gathered fromt that episode, American Christians also get circumcised..
