Sorry a case of mistaken identity cause of your remark
Well I am also not a fan of that content especially since is MMF as well. On the whole I am able to pass up those scenes for myself though if game focuses mainly on MC having sex and is not 10 NPC sex scenes against 2 MC scenes. If the second the game is just not for me and I am not its target player base.
That does not take away though that mixing it up has disadvantages especially in a more romantic oriented game. If go to more extremes as dp and MMMF you make a char even less desirable as a romance option for many, while satisfying the kinks of those that are not its core target. If the game is meant as an everyone fucks everyone fuckfest that is fine, if it has a more romantic goal that is less smart.
Edit: The aunt as she has now been setup will be a pariah for many of those that might have wanted to romance her, not even speaking about the one dick only crowd.
