Hermaphrodite

Hermaphrodite

A hermaphrodite or "herm" is a being which posesses the genitals of both genders.  Such a being may have the outward appearance of a female while posessing a male penis as well as a vagina, or alternately, have the outward appearance of a male while posessing a vagina as well as a penis.  A rarer version is a being with an adrogenous appearance (meaning they look neither male nor female) and both sets of genitals. The term "hermaphrodite" does not include she-males, which is basically a male with breasts, or a female with a male sex.

In reality, hermaphroditism is a real medical condition, though it is important to note that fully fuctional hermaphrodites do not occur.
