I sure feel something, some kind of bond, but I would never use the word "spiritual" to describe it. In fact, I don't really know how to put it into words at all. It feels like... something I was put here to do, as pompous as that may sound. That's what I mean when I say it's instinctual, like something deep down is triggered, telling me this is right, this is good, this is what I'm supposed to do.
But I thought about the spiritual sex you're talking about and realized that I don't identify with it simply because it's an experience I largely lack. Love is tricky for me. It's extremely rare that I fall in love... Which I'm guessing is more or less a prerequisite what you other ENFP's have been talking about.
This is a kinda weird realization, because that could mean I've basically been talking out of my ass this whole time, and that my perspective could change drastically once I jump into bed with someone I actually love. On the other hand, thinking about sex this way was kinda default for me... And I'm not sure that would change if I had sex with someone I share a stronger bond of love with, because that's what I naturally feel about it. I can imagine that it adds another dimension to the sex and intensifies it, though, which would be mindblowingly awesome because I already love it so much.
