It sounds like it's erotica>romance. You'll find, though, that most books fit into multiple genres, and when you publish it, you can list it under several as well. Genres are a 'softer' designation than they used to be.
Chris is also right, 200K is way too long for a Romance book. Readers frequently prefer longer books, but you should be aware of genre limits. Romance and Mysteries tend to be shorter (by a significant amount), while science fiction tends to be longer (because there's so much back story to cover). A visit to your local bookstore will give you a decent idea of what the genre standards are (just discount the big name titles, since those authors have earned the readers' trust).
I may be making assumptions, but with a name like "Lumpy", it needs to be said. If you're writing a Romance, you'll probably want a pseudonym. It's more effort, and won't help you publish any other books under your actual name, but it's another genre specific detail. Most romance readers won't read a Romance novel written by a man. I suspect you could get away with it if you're writing Erotica>Romance, though.
The thing to remember about publishing, is that first books don't sell well. The first thing many readers do, when they see a book they're interested in, is to Google the author (by the way, you may want to look into a website as well). If they don't see any references, or if they only see a single book, most readers will pass it up. There are just too many first-time authors who get discouraged and never continue. The more books they see, the more likely they are to purchase from you.
But don't worry, you'll make it up. Every subsequent book will help sell your earlier books. Assuming your readers are satisfied, you'll earn their trust. That's why serials are so popular with publishers now. Many traditional publishers are now discouraging first time authors with only a single book, telling them to come back when they have a trilogy (sounds counter-productive, I know, but what can I say).
As Chris says, you want to keep the first book in a series short, so it's easier to give it away free (and for a reader to read quickly). Selling a first book virtually guarantees later sales (they decrease over time, but stay largely consistent). The key is to charge little (or give it away for free) for the first book in a series, and to charge the most for the final book.
I'd keep the other books (after the first) between 50,000 to 80,000 words, just because of the genre standards. Rather than cutting them at that size, you'll do better editing them down. If you keep in mind what the readers expect, it's easier cutting the scenes you personally love. :(
I'm not sure what the 'average length' of erotica books is, since my local book store doesn't keep that category on the shelves.
P.S. As for SOL, they prefer longer books, so you could post the entire story, but it's a bitch maintaining separate copies of a book. So I'd recommend you post whatever you publish (you don't want readers expecting to get more by reading your books for free).
