An NTS tag doesn't mean the game has to go from 0 to 100 right off the bat, no? It's part of the game and our protagonists are getting into more daring situations over time. Me personally I'd prefer for it to have a reasonable pace with characters evolving rather than them going all-in on something that is new to them.
We went from light exhibitionism at the beginning to a handjob in Ch05 - with lots of in between. Not sure what you've been playing, but I'd say that is way beyond dirty talk. I think that's fair, and personally I wouldn't want to see a young inexperienced couple that just got together engage in full on gangbangs at day 01.
The game has an anal-sex tag aswell, but that doesn't mean every sex scene has to be centered around anal, right? The same way a masturbation tag doesn't mean Eric's gotta walk around beating his meat in every scene.
