I learned something about sex, genetics, and animal anatomy and behavior in university. As a farmer, I deal with these realities every day.
Humans are mammals. We may be anywhere on the sexual preference spectrum, but we are physically male or female, to the core of our DNA.
Not always, and probably due to our consumption of chemicals which affect hormones, it seems many mammals and lower life forms (frogs esp.) are increasingly exhibiting sexual organ duality or lack of differentation at birth, requiring an assignment of gender for a birth certificate. At puberty, some develop contrary to assignment and lived experiences. These used to be called hermaphrodites and have been known from ancient times. I wonder that you, as a farmer, are not aware of this in animals at least since the internet has so many pictures of two-headed calves, snakes, etc. If nature is capable of duplicating the most complex part of the anatomy, sexual organs should be much more common.
