In defense of Q, I have to admit that he articulated several of my thoughts on this topic. We see so many doms on this forum seeking subs, I imaging many feel hurt, cheated, frustrated to see doms with multiple subs. That said, I hope they will see past the frustration to see the hope - subs flock to those they perceive to be good, experienced doms. To those subless doms, I advise you to observe and learn from the behavior and comments of these doms with multiple subs.
Personally, aside from some occasional casual play, I could never share a dom. My ego is far too huge. As Mina said, I would interpret it to mean I am not enough, and if I am not enough, then the relationship is not right for me. I wouldn't even bother with an ultimatum. If a dom said he wanted another sub, I'd be outa there.
Although it's not for me, I can actually understand poly in real life more than I can online. At least in real life, one sub doesn't necessarily take away time from another sub. All can play together and share chores, creating more time for play. But online, it seems to be a mathmatical fact that one sub does take time from another. There are only 24 hours in a day - estimating at least 9 spent at work, 7 spent sleeping, 4 spent on meals and traveling to and from work, 1 spent grooming, 2 spent with the wife and kids, that leaves an hour a day to play. I want that hour, every day. I don't want to alternate days or wait until weekends. Moreover, when a dom is thinking about another sub, that is time he isn't thinking about me. I want a dom who spends as much time thinking about me as I spend thinking about him. We've all sympathized with Silke when she has spent days without any contact and have seen how emotionally difficult that is for her. No offense, but I can't understand settling for an hour of somebody (no matter how great that hour may be), unless that dom is just a temporary stop during a search from someone who can commit his whole self.
If I've offended, I apologise. I'm just stating my opinions. Unfortunately, I'm extremely opinionated. However, I don't mean anything personal by my opinions. Let me state for the record that some of my favorite doms at this forum are poly. I, like Q, just don't get the psychology of poly, and hope by stating the problems I have with it, you all can (and are willing) to explain why you don't have the problems I perceive. Another thing I am really curious about is why anyone with a live-in sub, would seek a serious relationship with another sub online.
