There are real consequences of sex though: pregnancy and communicable diseases. Some of these can be mitigated (e.g. modern contraceptives), but I think they are at least factors to consider in favor of monogamy.
That said, I believe that life-long monogamy (as would be prescribed by marriage) is fighting against human nature.
I think that what you’re describing is not conducive to monogamy but rather secure and trusting relationships in general. I think many people tend to assume that quality exists within monogamous relationships whereas they assume non-monogamous relationships to be more frivolous.
Would you expect an unwanted pregnancy to be handled inherently better simply because the relationship of the parents is monogamous. I would think that’s entirely up to the strength of the relationship and the maturity and means of the people involved, regardless of orientation.
Similarly with communicable diseases, I don’t think non-monogamous people are any less capable of practicing safe sex with people that they trust. Of course, it would make intuitive sense that the more people you’re exposed to the higher your chances are of contacting something but in reality there is no significant difference in the rates of contacting a disease between monogamous and non-monogamous people.
