Translation: no one in this situation values anyone else in this situation highly enough to want to be exclusive with any other person.

The minute anyone starts caring more about someone else here, than he does about his own personal appetites, there will be "jealousy."

These sorts of things are attempted all the time - they are temporary for a reason.

You are right. Not a situation that will last forever and eventually when someone really starts to care about someone, the jealousy will hit the fan.
