There is this medical term "true hermaphrodite" so yes, it is biologically possible, which is the very reason I asked you to look up medical research. Maybe not to the exaggerated scale but it's very much a realistic thing.
Maybe you didnt get it the first time.
Futanari are fantastical perfection, not a reflection of what is biologically possible IRL. Futanari may have been inspired by IRL hermaphroditism(check the old Japanese medical scrolls) but it is not meant to be a reflection of it. They do not exist.
Further, the origin of Futanari as we know it is literally from hentai...that people fap to. No offense to anyone but I do not know of the real life condition existing in any form that would elicit that sort of reaction from anyone. But here you are, complaining?(or are you just bringing up irrelevant medical trivia for shits and giggles) about anatomical "incorrectness" in fucking porn game for a disorder that is 99.99% of the time a net negative....
Moreover, if you look at all the fantasy beings like beast people/succubus/etc, they have human anatomy
To make them relatable/cool/attractive. You aren't going to form an emotional connection to an entity that looks like an amorphous blob or something that looks like it evolved for the sole purpose of eating you. mind blowing.
just as I find having 2 sets of sexual organs.....
I understand why you would find it, even perfected in a fantasy setting, unappealing. But you have a few simple solutions...Get the fuck off? Blacklist the tag? remove it from your list of visible games?
Why are you in this thread? to consume content that you fundamentally don't enjoy? I think there is a word for that and it doesnt fall under the umbrella of rationality.
