The closest I can think of is when you're still on the romance path with Karlach and fix her up in act 2. You can then tell her you're okay with talking during the night but want to keep your boundaries, and while she accepts that, she will still be very forward during the long rest dialogue (it's the same dialogue as when you tell her you want to spend the night with her).

However, in case of Karlach, she will take no for an answer if you say no then. And in her case, it's actually expected, too. She's given all the hints to that point that she's in serious need of some loving after not having been able to touch anyone for years, so just willingness to talk to her, boundaries or not, is enough for her to give it a try.
