Your 'futa' don't have a vagina so they're not hermaphrodites so that means they're not futanari. They are just 'natural' shemales that didn't need to take hormones or plastic surgery to get breasts and get a amazon physique through a second puberty. If you're annoyed that people constantly remind you that your futa isn't futa all you don't need to show your lore to 'prove' they are actual futa. It comes off as doing mental gymnastics. All you have to do is just give your futa an actual vagina and people will stop complaining. That's literally it.
