I have no idea. I’d say that if you experience a lot of sexual attraction than it doesn’t sound gray-a to me, but if it is limited circumstances than it very well could fall into the gray-a category. I guess in your position I’d be asking myself why it is primarily fictional characters.
You’re the only one who really has the answers. I can provide definitions and opinion, but I’m not some arbiter of labels. I’m just a gray-a person who spent a lot of time figuring out how they identify.
