Well you are in a brothel discussing an agreement with sex workers, she is just faster that Tav to understand what are they talking about. It also procs only you talk to them first time. Personally she rejected them first time and if you come there 2nd or 3rd time after first visit(regardless of outcome) there is only your character that initates it. Of course it could be changed same as Mizora fling, but I wont call it "first" priority in that case(Dont get me wrong, I would prefer her to be less comfortable sharing too.
I think it'd be odd for her to say that even if you said you wanted it, but right now she says it while all you are is inquisitive as to why they're there. Remember, you're not even in the brothel for the usual business, you're there to chat with Voss and Raphael, and potentially more quest NPCs. Of course, now I'm sort of reaching, you DID actively start talking to prostitutes, but in my opinion it should be you saying yes first, and her reaction doesn't fit character (after the swimming scene).

Disapproval thing stinks as much too though).
You have though. Any situation where you do anything with another companion, such as kissing Wyll after your dance, and can talk about poly. She's not okay with it. Done deal. They just retconned it for no reason in act 3.
As for the swimming thing, she does talk about still having sand in her hair the morning after, heavily implying that the rest will know what happened, so him knowing I don't mind as much as the dialogue itself. Just imagine how cute it'd be if he asked what happened (with some implication he knows) and she says you two ran off to make sand castles. Instead, we get this.
