I don't know how to tell you this...
This game is about the story. This game is about the relationships. This game is about resurgence and rebuilding.
This game isn't about sex. This game isn't a Medieval Fantasy. This game isn't about p0rn.
You came to this with the worst possible expectations, expecting a p0rn game. It has sex scenes, yes, because sex is part of relationships between adults.
But, when you call a finely crafted story "meaningless fight/ dialogue", you completely missed the point. So badly that you're not even in the same Universe.
I am going to speculate, that you progressed by skipping looking for the sex scenes, not bothering to read, understand, immerse yourself in the story and in the world.
If that is the case, you have no one else to blame but yourself. You and this game are not a match, that much is obvious. This game demands that you think and feel, you aren't available to do that.
If I may suggest something, it is better for you to search for another game more to your "needs", because playing a game heavily geared towards reading, when you don't read anything, will NOT work.
TL/DR: It's not the game, it's you.
Peace
