I don’t mind including sexual content; to some extent it can make the characters feel more vivid, and at certain points it can also show that the relationship between the characters has genuinely progressed. If you’re worried it might affect some players, you could add an NSFW on/off toggle in the settings (though I’m not sure whether that would create extra work for you).
Also, Happy New Year to you! I’m really glad to see the developer actively engaging with players~
