Yeah, that vocal minority insisting on seeing two men go at it in a game about the player and Anna is kind of odd to me as well. It sort of matches the world setting, so I can sort of understand why it's there in this case. It could probably also just be its own game, though, if we're being fair.
The very obvious solution with including kinks in your game is usually to just make an alternate version of the kink scenes with an option to toggle the content if you want. Making that content is a big time sink already and having most of the people just not even engage with that content only makes it a bit of a waste of time otherwise.
