I think many people here are mistaken when they call what happens at a party "romance". This is not a romance start... In DOS2, you could also sleep with Fane "for the sake of science", there were no problems, it was not start romance or a BIG relationship. I think problem is not characters, but how people perceive this night. If I have 3 bed scenes in 3 acts, I'm all for it. I don't see this as a problem, and behavior of Astarion and Lae looks normal to me for their personalities. The only "sex doll" right now is Shadow, haha, even without an intimate scene. Because people wanted her to be nicer... Disgusting. Changing personalities of companions for tastes of player, this is much more dangerous than what you are talking about here.
