Energy Exchange Question

[Coordinate_Apotheosis]

Depends on the surrounding experience.

I can't say of yellow ray, but green and blue ray will play a part with love and communication in the physical exchange.
Indigo I think would be a tantric or deep spiritual connection, a sort of melding.  Maybe it could be called fusion, I don't know.

I can only speculate that the yellow chakra is activated immediately during a communion between two currently socially involved people, versus just 'plain sex' intercourse for sexual satisfaction between two people who don't really know each other peaking at orange ray.

Of course chances exist and even plain sex has the ability to evolve right there in the moment to a loving interaction, and maybe higher.
