Rather than reinvent the wheel, why don't you take time to search the term triad and find out all the pitfalls of basing your desire for polyamory on the FMF triad so popular with men? (There is
so much porn based on one man/two women fucking, and so many men jack off to this and decide this must be that polyamory they've heard about, and that they want to make this happen in their lives. Guess what? It's not.)
I am currently reading older threads from our Poly Relationship forum, which go back to 2009. There is just a wealth of information. Here is one I am currently reading, for example:
To succinctly answer your question, the definition of polyamory is: Having or desiring to practice the art of managing multiple adult, romantic (usually) sexual relationships, with the full knowledge and informed consent of all parties.
It's
not hawt threesome sex with your main squeeze and a hot bi babe. Triads do exist, but they are
extremely rare. By far the most common configuration is a V, where one person dates two other people, but those two people are platonic friends as best, or merely acquaintances who are aware each other exist, but may never actually meet irl.
