Bumping this up because I would also like information on this. I've just started up a resource site for erotica writers. So far, I've only listed at blog directories, however, my next step is to get listed in some of Yahoo's and Google's directories. Have you tried those?

Maybe surf the net and do link exchanges with other adult content websites. Not all of them are neccessarily porn. Look into erotica writers and artists as well as other forums where the main subject is sex such as Literotica or Desdmona.

I'm new to the marketing arena myself and really don't know what I'm doing but I hope these suggestions help anyway.
