How Controlling One's Sexual Life Had Begun

This article on the Discovery News website reports how this rite of passage begin. "According to the 6th century A.D. Greek physician Aetios, the cutting was necessary in the presence of an overly large clitoris. Seen as 'a deformity and a source of shame,' the clitoris would produce irritation for its 'continual rubbing against the clothes' thus 'stimulating the appetite for sexual intercourse.'" http://news.discovery.com/human/female-genital-mutilation-begin-121210.htm
          Right. So, if it were a deformity, why is half of the population of the world are born with it? Why is the 'continual rubbing against the clothes' considered a form of irritation when it's just doing what nature intended it to do? Why is it shameful to be 'stimulated for sexual intercourse' as a woman? This 'practice' is nothing more than a tool to determine that women are prohibited to feel any pleasure of this sort due to the archaic notion that women do not and/or are not supposed to enjoy anything sexual.
         The article goes on with the Western history of FGM, with the procedure going in the United States in order to 'cure' things such as psychological problems, masturbation and nymphomania. Even if a victim of this terrible practice had nymphomania, it cannot be 'cured' with the physically and mentally painful practice of FGM. It is a neurological disorder. A medical disorder. Not of which should be dealt with by extremist, sexist moral or societal oppositions that lead to FGM.
          In the Victorian era of history, female sexuality was considered' diseased'. The first chapter of "Nymphomania: A History" by Carol Groneman goes over this bewildering concept of the 'problematic female sexual mind' and how masturbation as a female is was termed 'self-abuse' or 'secret pollutions'. http://www.nytimes.com/books/first/g/groneman-nymphomania.html
