For me, the biggest eye opener was hearing about a transgender woman who used to be straight as a man, but now as a woman had become a lesbian.
It was a real eye opener for me, because it told me that gender identity and sexuality were not automatically linked; they were (or could be) independent of one another. The guy's straightness did not disappear after he had become a woman, so she became gay.
Thank you for writing honestly about yourself and the truly fascinating human world we live in. I agree that we can be ourselves, even in our staunched positions that can then later get challenged. We're all human.
