Long term relationships are not natural though. Even when you consider kids.PairPlusRoyalFlush said:Understood, but if you are ignoringthe entire purpose of sex and bonding (procreation) then "natural" is not the correct terminology to use.
We are forgetting that ancient humans lived in tribes. Entire communities raised kids not just the mom and dad exclusively. Sometimes older brothers, older sisters, cousins, aunts, grandparents, friends, etc. So we can then conclude that LTR are not necessary to raise kids AT ALL.
Often we think about ancient humans as being this family of three with a mom, dad and kid. This is not how it was though. Humans lived in large groups. The alpha male f*cked all the women.
Also, when I say LTR I mean monogamous ones. If both people are cheating on the side.. it doesn't really count.
So I stand by my original post. LTR are not natural or necessary AT ALL.
