Hermaphrodites are persons born with both a female vagina, and a penis.
Most go through life outwardly as females because from a physical aspect they usually look like women. They develop breasts, have a fully functioning penis, and also a fully functioning vagina, labia and clitoris. Their testicals are internal, so although it appears that they do not have balls, they do, and can ejaculate sperm as a truly functioning man. Most hermaphrodites can father children, and also conceive children. Theoretically they can fertilize their own eggs, so they can be both father and mother to the same child.
