Yes, and the word comes from the story of Hermaphrodite, a son of Aphrodite, getting into some shenanigans and ending up cursed. Since then it's become a general word for joinings of opposites into a single form.He's wrong anyway, herm is short for hermaphrodite, which is a medical term for any being with both male and female sex organs.
But again, when talking about which framework various hermaphroditic character types are based off of the character of Hermaphrodite represents a type starting from a male base while futanari starts from a female base. You'd basically only reference this to explain the differences between these which is what we were talking about at the time.
