Questions of a weird mind

Fair enough.

For the sake of technical correctness, I should point out that nothing more than the urinary tract is required for a man to urinate. The rest is...superfluous.

And only the bladder is required to generate a need to pee...

Also, if the eunuch says "I'm a guy", I would say he's a him. If the eunuch says "I'm a girl", I would say she's a her. If the eunuch says "I'm an apple", I would see how the apple tastes.
But, biologically, they're male, and the question of pronouns is one of gender, not biology.
