| We've talked about this a few times, but I cannot recall the threads because sometimes they're off-topics..
It's a matter of culture. Most of us live in a society where monogamy is what's considered morally correct. If you deviate from that thought process, you're viewed upon as "wrong" because that's not what the majority thinks and a people are not easily changed. They stick to what they're used to...but we are becoming more liberated, as you suggest.
That's the easy explanation. It doesn't mean it applies to everyone, but it applies to most. You won't find many people to agree with your reasoning, logical as it may appear.
As I've stated before, I happen to be one of those who tries to see things as you suggest above..logically.
Now everything is as complicated or as simple as you want to make it. You can throw a couple of other issues into the mix: children being the biggest one. What do you consider to be an appropriate upbringing for a child? In this love triangle...or love square you've set as an example, does the child have two fathers and two mothers? Again, I would agree there is only precedent to argue against having this but nothing concrete.
Having said all of this, this isn't a new concept. Swingers practice what you proposed. You, my friend, are labeled a swinger...
