Circumsion in Muslims

Does the Muslim faith,or Arab doctrine (is there such a thing?) mandate circumsion?I know some of them practice the female version in hopes of lessening desire or enjoyment of sex,from what I’ve read.

How do they feel about the male and his equipment?

Muslim men are required to be circumsiced; its a ritual thing, normally done at birth, much as it is with Jewish men. Male converts to the Muslim faith are also required to be circumsiced.

Oh, and female circumsicion is not required at all by any branch of Islam - its a purely (and hideous) cultural thing.
