Stories where one of the main protagonists (or major side characters) do the following: - Explicitly state they're bisexual/pansexual. - Explicitly state they don't care about gender.
That's it really. I don't ascribe to proving/assuming their bisexuality by showing that they've got a past relationship with same/different genders. It's only important that the character says they're not restricted to being attracted to one gender.
