Theory
There is no such thing as a male.
The term male describes a separate sex that of female.
My theory dictates that males are actually a type of female that uses a half hermaphroditic mutation that seperates them from female.
Theoretically, a human "man" is a mutant female.
This is supported by the chromosomal genes.
XX creates female and XY is male.
A true human male would be a YY male, which can not be produced.
Discuss this.
That is why men have nipples etc, because they are part female.
