You humor me with your notions. You, The Student, has attempted to correct me, The Master. Many grins!
'Traits that might increase the prospect of polygamy' does not mean anywhere near the same thing as 'traits needed for polygamy.'
In your life, you might not have connected polygamy to sex and physical regimen. The sex and physical regimen always factored in a major way with my polygamous lifestyle.
Using your own libido as a primary measure, how do you rate your poly unit's libido?
Suggesting or encouraging people interested in polygamy to not make rules, IMO, reflects both an open-minded and free-spirited nature. Figuratively, you split hairs to differentiate rules from agreement. In your poly unit, you took in a marginalized and vulnerable couple. This may have given your way of thinking a prohibitive advantage at prevailing?
Also, again IMO, you overused the expression "out there"... and you did not provide credible sources to validate your sweeping generalities.
For me, I found cash flow exponentially more complicated and important to maintaining polygamous relationships than a single monogamous relationship.
In your relationship with me, I came ahead of you in this world, thus, you remain the student.
As an aside, if you ever familiarized yourself with Voltaire's book Candide, Voltaire preaches a simple concept: work keeps three evils at bay- Boredom, Vice and Need.
Peace to you and yours! Keep us updated on your poly unit.
