I can only think of 4:
male
female
eunuch
spayed

[Only1choice____Freedom]

With the possibilities there can only be four:
Male
Female
Both
None

99.9% fall into the first two.
.099% are both or ambiguous at birth.
.001% are neither. I have only known of one.

Anything else is mental and unrelated to sex.
