The author does not use a single word of emotion to describe what he calls "backstage intimates", so I reject this label for the kind of friendships I talk about. I would primarily describe them based on emotions! Intimacy, platonic love, deep appreciation, being confidents!
The greek storge variant of love comes closest to what I am talking about. I have three friends like that, I trust them on a deep level, we often talk about our deepest feelings, in complex ways they love me and I love them. I even share physical closeness with them, when we meet we are as close as a long distance couple that just met again in real life. With two of them I occasionally have sex when we see each other, opposed to my FWB I do not have a connection to beyond sex. They are beacons of light in my dark life and among the most valuable things I have.
The semantics aren't too important to me, but my gut says no: What else than an extension of platonic love is it, if you can combine and the trust and affection it creates with mutual physical attraction that culminates in sexual relations?
