I'd think that some of the more literary erotic publishers and magazines would be interested in erotic poetry.
Think of unconventional markets, as well. I'm working on a piece of erotic poetry no more than 20 or 30 sentences, to be turned into a book art sculpture/jewelry piece later this year. Basically, each bead will be a word, and they'll all be strung in sequence on a scarf-like piece of body jewelry. I'll have a smaller text-on-paper version as well. The grouping will sell for around $600 or higher as one unique sculpture. If I could figure out multiple production I could do an edition of 5 or 10, and make even more money. Not all at once, since art takes time to sell.
I'm getting a lot of book art clients who are not averse to erotica with their art - it's an old and honored tradition.
