There is already a word for this.
It’s not a sexuality, it’s an attraction called fictophilia. What you’re describing is an extreme case of it.
You can still identify as a certain sexuality and be only attracted to fictional characters of the genders you specify within that sexuality, henceforth “fictophilia,” not “fictionsexual.”
THERE IS A POINT WHERE THIS SHIT NEEDS TO STOP, AND WE HAVE CLEARLY PASSED IT
Delete this whole website just do it
calling this a separate sexuality instead of a -philia is actually so problematic can tumblr please just stop
