Oh my! She must have been with both male and female Intersexual!

My mother had a very close friend that grew up as a man. She had children and everything.. but then decided to become a woman because that is where she/he felt more comfortable. She had the hormones for both male and female. Although I am not sure if she could procreate as a women like she did as a man. 

These types of "sexual" confusions are more confusing to us as humans than they are in the natural world. Cases of clitoral hypertrophy (a penis-like organ on the female) is quite common in nature and is actually the "normal" condition in many types of animal (such as the hyena and the spider monkey). Similarly, undescended testis are common in elephants. It becomes confusing in humans because much of our role in society is determined by sex. If we don't know whether someone is male or female (whether this is due to biological ambiguity or some type of cross-dressing) our culture does not instruct us well as to how we should interact with that person.
