I think all writers are armchair psychologists to some degree or another, and I think a character's sexuality is fascinating. It's a great way to really get at the root of their identity, because it's such a personal thing.
I certainly believe that what we perceive as humans is just the tip of the iceberg. I don't necessarily believe in vampires or werewolves or that kind of thing, but I believe there is definitely a realm we don't necessarily have access to.
Life is suffering. We have desires and expectations and egos, and we compare the reality we have, which is miraculous and wondrous, with this reality we desire. That somehow distances us from actually taking part fully with the reality we do have, and that creates suffering. For me, the thing that I love is that it's all about the present moment.
