@JTT,
I am sure the INTENT was to destroy sexual pleasure so as to gain men more assurance that children were their own...as is common with such things it is now surrounded with endless pseudo-reasons having to do with religion and culture....the thing becomes self-perpetuating as the ridiculous "logic" of "everyone else looks like this, she'll be rejected, impure, undesirable etc. if we don't do it" takes hold. (Remind you of anything?)
Different types of female genital mutilation exist with differentially extreme results.
The type Greenwitch is referring is the most brutal, I think. As I mentioned earlier, I am sure that emotional trauma and the horrific sequelae of such brutal and frequently dirty and un-anaesthetized mutilation can rob women of all sexual feeling, or, indeed, create intense and lasting pain.
Nonetheless, excision of the clitoris does not, in and of itself, rob a woman of all sexual sensation. This, at least, according to the accounts I have read from women who have experienced it.
Female genital mutilation does not necessarily include the horrible practice of infibulation.
When it occurs, that is certainly a very dangerous and horribly degrading practice...especially as women have to be cut to give birth, and then re-sewn.
One of my friends worked as a midwife in England, and was full of horror stories about this. Including women returning to hospital the day after discharge with their babies, with the need for surgery after having been raped by their husbands.
