Am I really asexual?

Ive identified with the term asexual for a really long time but I’ve been watching some of psych2gos videos on it and I’m starting to question it. I am without a doubt sex repulsed, but in a psych2go video explaining the difference between asexuality and aversion due to trauma, they talked about how most asexual people aren’t averse to sex. They also talked about how asexual people don’t experiment with sex in their youth, but I did and that’s where most of my trauma comes from. But the thing about it is that i don’t like calling it a disorder because that implies that it should be fixed, but I don’t want that. Is it possible that I became asexual rather than always being this way or is it really just a disorder? Or is it insulting or wrong to call myself ace if it is a disorder?
