I am not opposed to romance in an RPG. I am however wondering why it has jump straight to romance and sex. Why not build up more, start with a friendship that gets you into the NPC's story line. The friendship deepens as the story line advances and you gain the benefits of friendship. Then at the end of the NPC storyline, give an option to take it romantic so the romance and sex is the "climax" of the storyline instead of the entry point.
