The question is not one partner versus multiple partners. The question is whether any of these partnerships are any good.

If one person or a group of persons is really able to give you that which would fulfill your life, then you just cannot be stopped; you would say, “I am prepared to lay down my life, but you cannot stop me from being with that person.”

Mostly these flings are blind attempts at getting from people what people cannot give, and using ways to reach destinations that those ways cannot reach.
