Eh personally I don't mind lesbian stuff, especially when it leads to ffm three ways, then even better. Only when it's a male protagonist game and you have way more lesbian content than the male MC getting his dick wet, is where it becomes a problem, "for me" anyways. Everyone has their own kinks, including the devs. Asking the dev to drop a scene in a game because you don't like lesbians is also going overboard. Plenty of other recent games have been adding nonsense lesbian content that has nothing to do with male MC, just for the sex count and to keep the player hungry I suppose, I don't think this game falls under that.
End of the day, If you don't like a game's content then don't play it, I don't like ntr so I don't play ntr games, pretty simple. We're all also on this site for a reason, to play the games for free, so we don't have much room to even complain in the first place. There's tags plus the genre spoiler on every one of these game pages to tell you the content you will be getting, you can feel upset if something changes mid game like the dev suddenly adding ntr, but not when it's already been labelled before you even downloaded it.
