I don't think you have been penalized either... just taken back in the search engines.
You can always check if you have been penalized...
allinanchor:key words here... in google search.
If you were too show up on first page for asian pornstars it would show it there. I think you have been bumped down the line
Look at your pages... splash (what a waste of a page) no keywords anywhere... your first page, all your keywords are in an image...
Just overall you have so little for google to wrap around and index well. You had a good string... time to revamp the site tour and think about things like H1 and keyword placement.
