Rubyspears,
True intersexuality is very rare. I would have to look it all up to give you the textbook correct answers. I know that much of the research in this area was done by a man named John Money ( I think). The original premise was to surgically correct these children shortly after birth. However, this is no longer done, because we know that Children usually do not have a clear concept of what gender they are until 3 y/o. Intersexual people made into 'men' or 'women' shortly after birth who then later discovered their core sense of gender identity was in fact of the opposite sex then had to proceed through through life in the 'wrong body.' The whole thing is a mess. I think kids nowadays should be able to express where they are in the male/female spectrum before anyone cuts anything.
