I will say this loud and proud. Futa is just a man with big ol titties.
Actually I dunno, I just saw this quote about futas and wanted to share it tbh.
This quote is about shemales, which are men who never had a vagina, but got boobs.
""Real"" futanari have vaginas, therefore they can be called: women with dicks.
In CoC2 example - Arona is a futanari, while Etheryn is a shemale.
Hermaphrodites have both sets of genitals. It's pretty simple to remember, but apparently not to westerners.
Edit: Whoever came up with combined futa/trans tag, should be flogged publically. The two terms could not be further apart.
