[...] always avoid selecting the “I want to know you better”-type dialog options for any characters that you don’t wish to bed. If you do this, you *might* be able to play the rest of the game in an immersive fashion. IDK. /shrug
But I *want* to get to know my companions better. Interacting with companions is like half the purpose of party-based rpgs. :\
I've always selected these options and haven't been hit on inappropriately by any of my companions (well, except for Lae'zel in the early game but that was in character and funny). Astarion and Wyll (eventually) did make moves but then my character had intentionally flirted with them a little. Noone else has, despite being friendly and curious about them, and Lae'zel and Astarion (who my character let down after a one-night stand) haven't repeated their advances.
Clearly it can and does happen, but I'd say that unless avoiding getting hit on inappropriately by your companions is such a high priority for you that you're willing to shut off friendships (and it's totally people's choice if it is), then it might be worth the risk of just going with the options you want at the time. You might be lucky like me, or you might come across some janky behaviour. but if folk are willing to give that a go and report as bugs issues where characters don't take no for an answer or even require a "no" when it should have been clear from our interactions with them that we weren't interested, there's hopefully more chance of this being fixed.
I am curious… did you enter long rests frequently in the early part of your playthrough and routinely talk to origins characters? This seems to be a viable strategy for avoiding much of the jankiness.
