I had read Heinlein too, but just assumed that like most concepts in sci fi that it was just made up stuff. My life is filled with sci fi's empty promises of future worlds where people live incredibly long lives, visit beautiful worlds, and of course, as equally untrue, have open relationships.
So I chalked the whole lot into the imagination bin of my mind, and didn't revisit it until 30 yrs later.
It was the Internet that made me realise that some beliefs that I thought were fantasy can or true, right now, in this world. Thats how i rediscovered my poly nature. If not for that, I would still be miserable and not really know why. It's been life changing to finally be comfortable with who I am. And it is my wife Aquarius who's given me the support to be myself.
Take the risk of thinking for yourself, much more happiness, truth, beauty, and wisdom will come to you that way. - C. Hitchens
