I spotted this open call for an antho with an interesting theme over in the Paying Markets forum at AbsoluteWrite.com:
"Ylva Publishing is looking for lesbian fiction short stories for an anthology. The protagonists should be involved in the publishing anthology, for example, a writer doing “research” for a love scene, a sexy librarian who doesn’t quite fit her profession’s stereotypes, a bookstore owner who has a secret crush on one of her customers... The possibilities are endless.
Stories can be romantic, humorous, or erotic.
Stories should be 4,000 to 8,000 words in length, previously unpublished, and written by a female author.
Writers whose stories are selected for the anthology will receive a one-time payment of $40 (via PayPal), two complimentary copies of the anthology in print, plus a free e-book in each format (epub, mobi, pdf).
The deadline to receive submissions is March 1, 2016."
