I think this is a valid question.

There seems to be gaming conventions, horror conventions, sci-fi conventions, anime conventions, buffy conventions,etc.

But are there any conventions specifically for porn writers/journalists?

The porn conventions that they do have now are either adult webmaster/website based or pornstar/fan based, that I know of anyway.

Wouldn't it be awesome to have a porn writers convention where you have a panel that answer questions, dealer tables set up with various types of fiction, mags?
