I suggest you do not submit just a few paragraphs, despite the fact they do qualify on the "very, very, very short" aspect.
But sure, go ahead and complete the story, and THEN submit it. Sure seems to me that meets the "written this year" criterion.
One story at a time, please. If you get a rejection and there's still time, you're welcome to send another, then.
As for hardcore erotica, this post states your options. The anthology will be a collection of speculative fiction. Erotic elements are allowed--even, I suppose, hardcore elements--but if the story is primarily erotica the chances of it being accepted is very slim.I know this was already asked but I wasn't really clear on the answer, is hardcore erotica allowed? More specifically, erotica with gays and/or lesbians?
Also, is poetry allowed?
