Really good visual Novel that does this that I would recommend reading is By Your Hands. Although the story isn't complete, what is there is really good. I won't spoil the twist of the beginning of the game but something o especially love is how the protagonist has a complete unique perspective on life. A thing that most stories fail to do is not be afraid to have different cultures or character cultures that can be blacker than gray sometimes. The protagonist's responses is great with how you actually having a horny response makes him obsessed with having sex rather than just the person themselves. Which is a great detail in my opinion. It forces you to have to balance out the horny and the love. I especially love how jarring the tone shift in the story is after choosing a route. But in any case, this game has that culture aspect with how the characters aren't all living under the same set of rules.
