Does anyone would the military accept a person into it's services that is a hermaphrodite ?

I will be honest that I am not sure, but I doubt it.
The trouble will be that because they have both sex organs and as such issues of privacy in the barracks during basics.
* and same issues that happen in prisions with them, they can't be in general population but have to be in protective custody (lock down) the entire time.
But as noted, if they were, there is obvious sex organs of both they would have a penis and a vagina both visible.
I can't say for all but as noted for the several I have known, there would be no way not to know if you saw them naked.
