Like many of us, I knew I was different from a very early age, and years later would find out that I was different. In this Youtube Video, pay close attention to the habits of the Flatworm, and the Clown Fish. Both spontaneously change gender. https://www.youtube.com/watch?v=DWlLPtaw2hw , 10 Bizarre Animal Mating Rituals.

I do hope that you can see the video without difficulty.

I think that this points the way to a biologically legitimate explanation to Transgenderism, though we may not get to the actual mechanism in humans for some time. In my mind, this should remove all basis for ridiculous moralization about gender change. And this may be an evolutionary step in the development of Space Sapiens who can change gender to suit reproductive needs.

I inadvertently alluded to this ability in "Alien Investigators", though at the time did not realize that would be important. Hmmm I feel a story coming on perhaps.
