btw,
1) humans are ominvores
2) males have penises
3) females have vaginas
4) the sun warms the earth
science is not complicated unless you're retarded to begin with
5) some people are hermaphrodites
So it is just a bit more complex than you may think.
But I agree 1 to 4 are correct.
As to the true % of hermaphrodites I have not been able to get a good number that I feel safe to state.
... it's true, hermaphrodites can have combinations of sexual organs, in varying degrees no less, but they are neither female or male .... but I was trying to keep it simple for people who are mentally-challenged to begin with
