I'm glad that Greta and a few others have opened your eyes to the possibility of polyamory, ethical slutdom, as opposed to lying and cheating.
Just want to point out that polyamory means many loves. It's perfectly OK if, right now, you feel Nisha is your one true love and for others you will only feel lust, "enjoy the moment," or at most, have "warm feelings."
But perhaps you're feeling more than that for Greta? What if warm feelings and lust develop into love? Does Nisha love her OSO?
And what happened on your Berlin holiday? Do go on!
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
