Those statistics are probably true. Quite a few African countries have a majority of females being circumcised at birth.
It's a myth that female circumcision destroys sexual functions such as the ability to orgasm and receive pleasure. In the countries where it's prevalent it's not seen any differently than male circumcision, because it isn't. Certain female circumcision is even less severe than the male equivalent.
In other words, I think Western prejudice is showing over this outrage.
Er...no.
Circumcision circumstances vary - sometimes much erectile tissue is left, sometimes not a lot is left, sometimes it grows back, and sometimes it doesn't.
In the many studies done on orgasm and sexual pleasure relating to female circumcision, there are some that state no difference - indeed, some report an increase - in pleasure.
But, in the words of my circumcised and widowed Nigerian friend, Happy (yes, Happy is her name), women in her village will rarely admit to sexual dissatisfaction because it's an enormous insult to men to do so. One simply is expected to defend tradition and custom. Even in secret, anonymous studies, Happy said she would only admit to being incredibly sexually satisfied.
Regardless of reality.
Haven't you found it interesting that according to studies, women in Nigeria have like a 90% rate of consistent orgasms and most of the world reports far less? Do they have a secret we don't know about, or are people lying?
