Part of the problem with replacing ‘herm’ with ‘intersex’ is that they don’t mean the same thing, especially in a fantasy setting.
A human with complete or partial male and female sexual organs is very unusual and I certainly understand wanting to be careful and not upset someone. ‘intersex’ is the word I would use (if they didn’t have a preference and make it known). Technically ‘intersex’ means a mismatch between the external and internal genitalia.
However, a Zi Ri from the World Tree RPG has both male and female functional bits, and the entire race is that way. (For that matter, quite a few invertebrate creatures in Real Life are that way, and hermaphrodite is the word used for it.)
Unfortunately there isn’t really an agreed-upon term in English for ‘shemale’ or ‘cuntboy’ (and I hate that word, but don’t have a better suggestion) for folks from settings where those are ‘normal’. Whatever ‘normal’ means.
I suppose you could put ‘penis-biased’ and ‘vagina-biased’ and ‘boobs plz’ as tags, but it’s unfortunately a situation where there’s not really a ‘right word’.
