Ashey : I think your friend means well, but her experience is clearly different from yours. I feel the way you do, if it helps; I don't always want to get bogged down in discussing The Trans so I don't highlight those bits of my past that are inextricably tied to being a boy, but as you've said, it *does* feel like all that editing adds up to a pretty big misrepresentation after a while. So it's great for her that she doesn't feel that way, but that isn't really going to help you.
And that's without even having a bunch of past relationships with women... yes, that must be awkward! (Can you tell people you're bisexual? I really am, so that helps too.)
