1, most definitely! the most prime example of that in game so far is Akarion prompting the BE from Rhianna (stand aside and dont challenge akarion, then go to the parapet to trigger the scene. the scene will happen off screen if you aren't there to see it). characters wont be making big plays of thier own until the mid game. the few characters that have influence right at the start are mostly waiting for good oportunities to strike.
2, we have a sex scene in game so far (written but not illustrated yet), and there will be plenty of nudity on the way! as far as adding sexual encounters, we want to have more, but they are a lower priority when compared to the TF content. that said, we do occasionally run polls on patreon that lets folks decide what sort of extra content is coming up next, which occasionally includes sex scenes.
