Um, ok, full disclosure - I edited the book and I work for Circlet Press (http://www.circlet.com).
BUT, Circlet Press published The Erotic Writer's Market Guide which talks about how to write porn and provides lots of markets.
You can also Google for "erotic writer markets" (and similar key words) and find at least three or four sites that list lots of markets for writing porn.
AND, last but not least, http://www.writersmarket.com/ is the online version of those gigantic freakin' books you see (like the 2007 Poet's Market). They add new markets constantly. There are quite a few erotic markets there.
