I don't have a problem with a route with lots of sex with every character that fucks up the relationship with the boyfriend and her reputation. What almost EVERY SINGLE AVN lacks is a good couple story alternative, it always seems to be the "Game over" or "sad ending" side of things. Seems like those writters have no clue on what to do with it haha. Sometimes I guess they are pretty doomed in RL.
The secondary problem with having sex with every character in every cliché, is that pretty quick runs out of ideas and then the novel is doomed, everything is repetitive or over exagerated. Anna for example, part 2, its almost doomed, not a single sex scene is really interesting, she had already fucked every single character.
