There's nothing unreasonable about asking for the option to opt out of Futanari content. It's quite literally the same thing as adding more of it to the game. I get people like certain fetishes, and I'm not saying they should remove it outright. I'm literally saying there should be the OPTION to play the way you want to play without seeing things you don't want to see. Such as cuckoldry. There's plenty of that going on here even if you're trying to play as someone with a harem, which the game could arguably do better to lean towards if that's what someone wants.
Not to mention the game literally uses AI and all the artists have to do is touch up certain things to deliver a finished piece of content. It's not rocket science and I get that sounds entitled but so is saying that Futa should be always present in every playthrough. If futanari players get their content, then people who don't want it shouldn't have to put up with it. It's not unreasonable to ask to not have futa in the game. Just like it's not unreasonable to ask to not have scat or urination scenes. There are people who are going to want to avoid those things.
