Sorry, but I think Yasuna is full of it.

Spoiler:

"Oh-noes! I can't see males!" Yeah, did that stop you from loving your dad?

It was never a matter of her "losing something", it was a matter of her "shoving something away, then deciding she wants it after all". Yasuna didn't even make an effort when he was a guy, but Tomari still cares about him regardless of what gender he is, even though she had to struggle with it.
