Okay, I’m back from the day job. The one where I actually earn my living.
I absolutely second the Erotica Readers and Writers Association at http://erotica-readers.com/ (entry page is work-safe). You will have to subscribe to the mailing list to post your own work and receive critiques, but you can also browse the vast array of information about writing and publishing erotica, as well as benefit from the calls for submissions. Members’ work is chosen monthly to be featured on the website itself. A lot of the writers on the mailing list are published in the genre.
Another good resource is The Fishtank at http://www.desdmona.com/ Again, intro page is pretty safe for work. You can join the Fishtank, and again, post and receive critiques.
You probably won’t get rich doing this, but you can make some extra money. You will have to write your socks off, though, and do a lot of submitting.
For paperback anthologies like Best Bondage Erotica 2 (my story is “Cuffed”) payment is between $50.00-120.00 US per story. From the time you write the story to the time it’s published and you get paid… Well, gosh, don’t wait around for that cheque to pay your bills. I’m talking a year or more.
Writing for money on online venues isn’t something I know a lot about, as I’m submitting for print publications only these days. (I’m also not writing as much due to the full-time job, commute, husband, dog, yard, housework, Christmas, and so on…)
Check out Clean Sheets www.cleansheets.com if you haven’t already. They’re now a paying venue, quite the coup to be accepted at, and feature some awesome writing. Ruthie’s Club just ruthiesclub . com if I remember correctly pays, too.
Good luck! Have fun. It is fun… If you have any other questions, please don’t hesitate to contact me.
