Not necessarily true—it’s possible you had an implicit “given that she is straight” at work when you were interpreting evidence. If you conditioned on her being straight it makes perfect sense that you’d have no evidence one way or the other from a blind prior.
(People conditioning on such things is extremely common—for a much less innocuous example, consider what “no thanks, I don’t want to” looks like to someone who is conditioning on “this person wants me to”)
You’re right, actually. This occurred to me when posting the above. I started from “She’s a girl who says she is straight” and then updated down to .9 based on what I learned.
One would hope that dating someone would provide enough evidence to make a better estimate than a blind prior.
