Beautiful story, all around. It sounds like a gorgeous place.
I think this, the culture of non-conformity, is what “scares” the so called normals so much. At least for some of them, I think, deep in their heart of hearts, they wish they could be so open and free.
I’ve heard for most of my life that humans aren’t meant to be monogamous. I don’t think this matters what sexuality one is.
Not everyone can handle it, I’ve seen it first hand. But for those who can, and are open and honest about it, it can be as beautiful as your story.
