Alas! No one has ever published one (which, considering the sheer amount of romance writers out there, they should), however, here (http://www.mondoerotica.net/sex-porn-thesaurus.html) are a few (http://www.sex-lexis.com/) I've found helpful (http://www.puncat.com/Adult/Arts/Writers_Resources/index.html). REALLY helped when all I could think of was "thrust" for about everything. ><

Seriously. Now I've got like, 2 books I think would be awesome to write. A Porn Thes. and "So Your Girlfriend's a Slasher" and then sell it at anime cons. *dork* ignore me, I'm rambling. Enjoy the links!
