Thanks for sharing. I enjoyed reading
I have some thoughts that may , or may not , be useful in sparking your own investigations.
Some parts of it may resonate with you,and some of it may not, so absorb what you will, if any 
( i say this because sometimes my train of thought runs in too many directions and the essence
of what i'm trying to pass on is clouded in the mist of too many other ideas
(( although sometimes these ideas are useful for my own further contemplation
))I don't find it surprising that many people have sexually influenced experiences with the spice. The universe is 'sexual' in it's very nature and all living things are a segment of the fractal-like multiplying process.
Our body isn't merely separate organs operating simultaneously, it's all an inter-connected system with signals being exchanged from the brain to areas of the body, and in turn, areas of body, sending signals to the brain.
Spice journeys can allow us to feel the whole spectrum of body , mind + 'beyond'
It sounds like your experience has reminded you to further explore the relativity of that spectrum.
Although, It will be difficult at times, it will also be ever fun, revealing and rewarding

Your thread title mentions the third eye. Our third eye and crown Chakra blossom and kundalini can arise and impliment it's self fully ,when
each of our chakras are opened at the same time. This includes the lower chakras, such as the root and sacral, which revolve around the physical/sexual/creative.

In order for a clearer and eventually abundant flow of universal energy to arise ( shakti/ki), the chakras need to be opened not just in 1, but in
both directions. From the root upwards to the crown (and beyond) and from the crown downwards to the root (and beyond)

In response to your explorations of relationships, and connections with others, You may enjoy reading this article about 'multi-dimensional relationships'....which is basically just a fancy way of exploring relationships from a holistic, and idealistic perspective

You never know, it may spark the thoughts and feelings that can act as the catalyst for the law of attraction to unfold and present to you, the relationship you desire.
