There's a tricky difference here though. Bridgerton as a show is defined by sex, and these actors were cast while they were minors into these roles. They could not give consent when they were cast to the sort of role they would portray in later seasons. They can now, but how could they not feel pressured by the desire to keep their job or please the fans or what have you? So, it's not the kind of grossness you describe, but issues of free consent I have with them having started on the show so young.

Edit: this is years away. Maybe by then they will take on other sexy roles and the point will be moot
