So basically, you cannot know what sex you are, adulthumanfemail. Without karyotyping, which determines your chromosome set, it is unknowable. Even with karyotying, there could be a mosaicism (so a mixture of, say, XX and XY cells) in your body. And it could really be anything, because in some Nature paper they found that mosaicisms exist. And there is even one paper, where a woman bore a child, and both, mother and daughter have XY mosaicism.
For some reason, the fact that said woman produced an egg (definition of female), conceived said child through her vagina and gestated the embryo in her uterus still does not mean she is female.
And oh those intersex conditions... Somehow, TRAs always hide behind intersex conditions. No matter how many children they have fathered - they are probably somewhere in the middle regarding the 'sex spectrum'.
As for clownfish: Clownshish can change sex (and so can humans, apparently).
Not sure about straberries, that was before my time.
