I've never been compelled toward a religion, or even a god, but I've always thought of myself as spiritual.
As far as my beliefs on God go, I don't know or care if there is a God. I have no control over it, I cannot effect it, and I personally am unable to communicate in any method with it, so I figure that even if there is a god of some form, it does not matter to me.
So obviously, my spirituality is different from many of the other people who respond here. I am more Self-Spirited than God based. My spirituality is pursuit of Eudaimonia, which I can't even provide a perfect definition of. I find quite a bit of my spirituality has to do with aesthetics, and the interaction between my physicalness and mentalness.
I have no doubt that spirituality adds to ones life, but I do not in any way believe that theism and spirituality are inseperable.
(oh, and the sex analogy is awesome)
Edit: And I feel the same as Abaya describes in her last post. I think all of the things she describes are parts of spirituality.
