I don't see the status quo changing much. I think relationships OUTSIDE of the norm might become more accepted or tolerated, but I don't see the norm changing because as I see it, it's exactly the kind of relationship that people in general are best built and wired for and is generally the most healthy for people.
If in the next hundred thousand years we evolve in such a way as to be wired completely differently, then maybe, but I don't see that happening with anything resembling the current "climate" of human interaction.
I'm not sure if it will, but I can hope sexually exclusive relations stay the social norm. It really devalues being sexual with someone if you're willing to do it with everyone, and if women are already looked at as pieces of meat, this could potentially worsen that view point. I don't feel that sexually open relationships are a safe thing either, emotionally or physically. I've seen too many people torn apart because people just don't know how to handle that kind of thing the right way. I really hate to see the day that having sex with just anyone you like, because then sex has no meaning left in it. And three, we already suffer from over population and rising numbers of teen pregnancy, being sexually exclusive does help control that, maybe not much, but it can help keep it from getting out of control. If we're not sexually exclusive I would hate to see what happens to our population then, more bad parents thanks to a kid they weren't ready for, and more bad kids because they don't have the proper parenting. More fatherless children. *shakes head* If people knew how to handle this type of thing, that's great for them but, most people don't know how to handle it, so really all I see is a lot more chaos if this sexually open relations thing becomes the norm.
I don't play well with others, nor do most humans when it concerns matters of relationships. Because we're hormonally driven and a fair part of that is defending what we believe is ours. Because humans like exclusive rights to one another for reproductive reasons, be it for purely enjoyable reasons or for actual settling down for a family. I mean men will kill each other over a woman and women will fight each other for a man. It's just one of the things about us as people, and the nature of all living creatures.
It seems like it. It's less stigmatized now than it was a few hundred years ago; a few hundred years in the future, it will probably be even less so. Society's gonna move toward something with more freedoms (hopefully!)
the point is what do we really want, and that would be a resounding exclusive arrangement; however, until this can happen, human nature what it is, we will flit from one encounter to another, basking in the less desired happenstance hook ups.
so it goes both ways, until we finally find the great exclusive arrangement we were really seeking.
