The Issue of Multiple Subs

Over time Mistress has hinted and teased me about getting another sub(most likely female).
This is not serious and may never happen but it comes up often enough that I wanted to give it some serious thought.
First let me say I am not opposed to the idea, but I have some concerns, mostly about how me and the potential other sub would interact with each other. Do you find that if a relationship develops between subs it makes things harder for the Dom or easier? I can't imagine that a relation ship wouldn't develop given the nature of a submissive.
Sometimes I think subs should live together in a commune and have the Doms come and visit. any way I'm asking for your thoughts on the subject, knowing there are no hard and fast answers to this question.

That's a tough question to answer. Each sub is different, and each dom is different. All i can do is speak of my own experiences. Having multiple subs is a reward in and of itself as long as your subs are getting along. The moment they don't, there's drama, and then it falls on the shoulders of the dom to put the subs back in place and remind them that its not about them, its about their mutual desire to serve the dom. this gets even more difficult if a romantic relationship, complete with feelings and emotions develops,a s in such a case, they may decide that they have to compete with the dom for their emotional partners attention, and that gets messy.
The idea is to pair up sus in the same room, but pair up subs that while they will get along and become friends, will not develop romantic entanglements. such as, putting two males in the same room, when neither of them is gay or bisexual. they can become good friends as they get to know one another, but there's less risk of a romantic drama ticking like a time bomb. the issue here at that point is the competitive nature to vie for your attention, but thats another matter altogether.
