I know a guy who says he was completely heterosexual until he had a particularly intense case of COVID that rewired how he thinks and feels in pretty significant ways -- now he's bi, and he's loving his newfound identity. Like you, I also know a wide array of trans people whose identities and attractions have shifted over time or as their bodies, social roles, or hormone profiles have altered, and noticed how my own attraction to people shifts or drops away as their genders change, too. Life is such a rich tapestry. There are so many ways to be!
