I just had a thought...

If there is already a struggle with each persons "place", would bringing in other slaves/subs make play disappear for the couple as a one on one basis? If both parties find that they are both Dom/mes, does this make them a team? I guess I haven't really read much on couples both playing the same role. And if they do both share the same role, do they share their slaves/subs as well?

I guess the obvious answer would be to each their own, but the idea of bringing in other people kind of sparked those questions as well.
