Writer's block

I seem to be making a habit of posting more than once in a single day, huh? I'm having writer's block.. Seriously, I don't know how to start, and I haven't any romantic scenes planned out.. I spent this afternoon scrounging and reading yaoi manga on a whim. There was one I really liked about a dark skinned guy who sought refuge at a church because everybody treated him badly. He had horns and a tail, though really, he's the hottest guy in the whole book! So yeah, actually he's an incubus who somehow got lost in the human world. So yeah, he and the priest began to have a sexual relationship *wink wink* it's even more enjoyable since it's so sinful, yet kinda sweet too. The incubus, while being kinda perverted and a tease, is at the same time devoted to the priest and kind of innocent. And it helps that humour was part of the plot, especially when his oldest brother, baldur, appeared on the scene. Yaoi aside, I really wonder if I can write such a story.. I seem to have lost my skill for writing. I have the ending vaguely there, where she follows envy to his death. Why? Because I love tragedies, and it seemed the only appropriate ending. After all, she's already the last of her long-forgotten kind. She belongs neither to the FMA world nor the world beyond the gate (ie our world, where seraphs aren't exactly common, nor accepted by everyone.) and in the beginning she never really had a purpose in her life until she began to turn into an aviaria drago during.. The full moon? But then her journey was driven only by curiosity. She never had anything to lose, nor was it ever her concern that amestris would later be threatened - though this attitude would not be immediately recognized by most, what with her cowardly 'I'm going to live!' attitude.
But I DON'T KNOW HOW TO START!!! Plus my writing style is kinda crap.
