basically he is bi but tends to date more men than women. Fia only has seen him date men so she calls him gay. Palmier sleeps with women but rarely dates them as he doesn’t think he’d make a good partner and he can be meaner to men.
overall the BS world men is basically bi in general since they don’t see gender as an issue and seem to fuss over species more, few exceptions being Ivar but his preference is more due to trauma, and had male crushes in his youth before that event
