There are different concepts of “trans” - one definition is anyone who has a gender different from their assigned gender at birth. That can include agender people who were assigned a gender at birth but no longer feel they are that gender and have “transitioned” away from it.

For what it’s worth, when I was pre-transition and repressed, I felt pretty openly hostile to gender and felt it shouldn’t really exist, and in general there was a kind of “ambivalence” to gender in that way. I would have probably said I would have liked to be agender or thought of myself as agender or non-binary, and certainly knew at that time that I was not my assigned gender.

So, just know that having difficult feelings about gender can be an sign of repressed gender dysphoria.
