include any hermaphrodite as both male and female for any pairings. Such that (assuming teens):
hermaphrodite+male = mf,mm,herm
hermaphrodite+female = mf,ff,herm
hermaphrodite+hermaphrodite = ff,mf,mm,herm
There is no way I'd make the reverse translation in those examples: to me "mf,ff,herm" reads as "there's a teen girl-girl pairing, a teen girl-boy pairing, and a character who is intersex."
None of those would encompass a genderqueer character - intersex (and herm) is body, not identity.
The codes exist to allow people to avoid content they do not/will not like.
My requested code could be used for just that, as I strongly suspect that there readers who find genderqueer characters distasteful, if not an outright squick.
