>In some species of flatworms, an animal can inject sperm directly through its partner's body surface. Scientists call this "hypodermic insemination". The first to stab becomes the father; the other bears the responsibility of motherhood. Mating then becomes a battle, commonly known as penis fencing. In some instances the fencing battle can last up to an hour. Some species even have more than one penis, making a more intense battle. The winner is the flatworm that successfully injects its sperm. The loser has battle wounds and carries the fertilized eggs - until the next encounter with another of its kind.
This is the origin of sex differentiation. Among other things, we evolved from hermaphroditic worms like those. Apparently, the development of specialized builds for impregnation and being pregnant was the most optimal way.

I've wondered about that for most of my life. My entire sexual configuration has been based around fantasizing about being female ever since puberty, and before puberty I can trace those feelings to a sense of empathetic humiliation over the idea other people are forced to be female.
I've never really been sure how much of that is due to me having been sick in the head as a little boy and assuming girls must feel humiliated about being themselves vs. how much of that is some actual way the world is that I was accurately perceiving.
