Personally I would offer that you shouldn't try to fit yourself into a category. We like things to be in their neat little boxes, but sexuality is on such a sliding scale. If you notice a man (online or wherever) that you find attractive and interesting, strike up a conversation. If you notice a woman that you find attractive and interesting, strike up a conversation. As other posters have said, keep working with yourself and having compassion for yourself and things will come along.
