For MM romance books that fall under the omegaverse subgenre, but instead of the traditional MM Alpha/Omega pairing (where the Alpha is the more dominant and the Omega is the more submissive in the relationship, and in some cases able to bear children), this list is only for nontraditional same-subgender pairings. Specifically Alpha/Alpha, Beta/Beta, Omega/Omega pairings.

The relationship dynamic must be equal, both sides must reflect their ABO label (whatever that means to the audience). There should be no "surprise" subgender reveal in the story (ie an MC that was presumed to be an Alpha, but is actually an Omega).

Also emphasis on books that see these types of relationships as a societal taboo, or claim that same-subsex mating aren't possible.
