[quote name='Strell']I'm not thinking about anything
physically related - STDs, pregnancy, etc.
I'm thinking about the mental artifacts that will occur. You're saying that not only do they
not exist, but they never
had a chance to exist, given the agreements reached up front.
'Course, this is where an argument enters about "well how could you ever possibly have a single relationship if you're effectively dilluting yourself across multiple people?" And the answer might be that a "switch" goes off at some point that shuts down any extraneous partners.
Personally, I don't (can't and won't) roll that way, and it seems pretty alien. But I accept that it's possible, despite my inability to truly conceive it.
I guess in that respect, I generally just wish luck to those in any relationships they pursue.
Lastly, I want to point out a tangent that I think somewhat applies and that I think is true - regardless of what women say, they cannot have sex without some faint component and concept of love, unless they are just completely doing it for monetary reasons. I don't think I've ever met/run across a woman who would admit to that, but at the same time, they won't deny it outright. They'd tell me I was insane and how I didn't understand and other bullshit, but when it came down to it, it was impossible for them to divorce such emotions.
And with that said, I'd really wonder about things.
But again, that's just me, and I realize I probably sound like a real jackass right about.....now.[/quote]
Oh believe me, my arguments run the gamut.

If you've ever had an argument w/ your gf, imagine that x3. And I didn't say they didn't exist. Far from it. Those mental constructs exist but over a long, long... LONG time of discussion, we've pared it down to pretty much nil. As I said, this is a difficult setup of a relationship & I don't think it would work beyond 4 people because, not only is intimacy a problem but logistics as well - who sleeps w/ whom? Do we all sleep on the same bed? Or does someone have to go sleep in the guest bedroom tonight? I hope I didn't give the wrong impression here. In a polyamorous relationship, every person loves everyone else. It means that the girls like to get frisky w/ each other as much as they do me. So I'm not completely hogging the spotlight. I'm just fortunate enough to be the only male in our foursome.
As to your tangent, what you said is pretty much true. But women have physical needs as well (and not necessarily from a guy either). To blindly ignore those needs results in a wandering eye. So if I'm (or the other girls are) not there to release her needs, a simple phone call tellin' us what's up & she gets the 'go ahead'.
I'd also like to point out that these girls can be just as jealous of outsiders hooking up w/ one of us (w/o our knowledge) & will react as such. It's quite the sight whenever we go out. Whenever a lipstick lesbian comes up to one of the girls turn on her boyfriend, the other 3 give the outsider dirty looks and pulls away our partner.
If you think about the nature of relationships now & look at what's happening, people are divorcing more often than before. Hell, in my own family, one of my uncle's already divorced 4 times.

And his pattern is the same, break up & the old chick & get w/ the younger model. It's basically serial polygamy. At least in our setup, none of us is fooling the other. If one person wanted out, it's effectively divorcing all of us & none of us want to give up what we have. It's just too good a setup. Everyone gets along (with minor arguments of course) for the most part.
