JP: Especially if you are the Dom, Alpha, Handler, etc, it's important to make sure you have the time, energy, desire, and ability to meet the needs of any you are taking under your wing whether it be 1 or 20. This includes mental and emotional needs, not just physical. Too often it seems pups want so badly to belong that they will jump in headfirst. Too often it seems there are so called Doms or Handlers who take on too many pups/boys/etc because it boosts their ego sometimes knowing full well they don't have the time/energy to add another person or persons to their pack or family. I am a huge proponent of poly and the complex relationship dynamics that seem to be more commonplace in the kink community, but we need to be honest with ourselves. Do we really have the space in our lives for another or perhaps would we be better off staying close friends or even regular play partners? Regardless of your role in the dynamic, it's ok to say "no, this isn't working for me" or "this is what I need to make it work for me". Beyond that, honest, open communication is vital. Jealousy management, compersion and emotional awareness are also key. And it's important to remember that relationships are not static. They are ever evolving, increasingly so as more people are added to the equation. Communication is a two way street and an ongoing process. Issues that could be worked out will build into something much larger and more unmanageable if you can't/don't talk about them as they occur before they can fester.
