EA will do nothing that jeopardizes the games rating so this will never happen.
Well I guess not unless we make noise about it. I'm not sure but I'd hazard a guess that the Player trait (from one of the romance aspirations) does work in gameplay in a somewhat similar manner as a Polyamorous trait would so it'd be totally doable to expand upon that to create a normal personality trait like that. I wish we could have it in the game. Well, I already have since I a have an "adult" mod that includes it but can't say I use it much but I like having the option.
