Hopefully your partners understand
that you do take into consideration how each of them might feel as this situation plays out. When partners fully understand where you are coming from, many of the potential problems you are taking the time to foresee deal with appropriately never turn out to be problems. Sometimes it has more to do with all of you being on the same page than it does being able to foresee potential problems.
Partners and metamours seem to be the most considerate during these minor dilemmas when you all do understand each other which is just another way of saying there are no misunderstandings.
