I don’t have any evidence past my own anecdote (who tf even studies this?) and I know what I went through. I was exclusively attracted to women (even if I found it disgusting) on T and then E and prog made me attracted to men.

There’s no evidence it doesn’t happen, because it’s only been studied in the context of cis gays rather than trans ppl.

Best evidence we have is most ppl are het since they’re mostly cis and hence would have the hormones that “are more likely to make them attracted to the opposite sex” but that’s a stretch tbh
