Interesting reactions!!
Steve 2 mentioned threesomes. My friend's case is not a threesome. He and his partner's experience is more like a trial and error experiment in an orderly succession for the younger partner, in finding a new partner before the demise of his previous partner.
If he waited, until my friend died, he may have missed his chance for a new life partner who really attracted him.
But since Steve2 mentions threesomes, let's look at a bible example, according to Leviticus 20:14 "And if a man takes a wife and her mother, it is wickedness,"
So maybe that was a problem among the proto-Israelites.
And, since YHWH blessed Abraham and his multiple wives,I guess we can construct an argument that YHWH blesses men who want multiple partners.
And many followed Abraham's example,. for instance:
Jacob’s sex life is more bizarre still. He purchased his first wife Leah from her father, then married her sister Rachel. Rachel’s servant girl Bilhah soon joined them “as a wife” for at least two children [Genesis 30:3-4]. Then Leah’s servant girl Zilpah made it a happy fivesome [Genesis 30:9-11]. Just imagine the happiness of Jacob with 4 women in his bed at once, (Not sure how they all participated at the same time - but the bible does not forbid anal sex with women.
and more XXXsomes followed:
These lucky guys were not alone. Lamech took two wives. Esau had three. Gideon had many wives. King Solomon had 700 wives and 300 concubines. ( Can you imagine that these women waiting for Solomon to pick them for a night of fun, did not have lesbian sex with each other?). Rehoboam took 18 wives, and 60 concubines. Abijah had 14 wives. Caleb had children with at least two partners. David had eight wives, an unknown number of concubines and a relationship with Jonathan (Jonathon was better than women, so David declared. What do you think he meant by that?).
There are others we know of and many we don’t.
Then jesus comes along an spoils the party, forbidding divorce and remarriage and alsoPaul saying elders should be husbands of one wife (could ordinary members of the christian congregation have a 3some?), although it is suggested by some scholars that bible writers wewre influenced by the self-declared Roman god, Augustus, who before jesus got going, made a law forbidding divorce and remarriage,
All that, of course, raises the question of whether humans are really monogamous?
Finally today, I'm curious. caves sees red flags flicking up, but what aspect of this discussion are the red flags flagging? He does not make clear what he fears.
