Did you try posting to the Indexing and Ranking section of Webmaster Central in Google Groups? Just make sure you put NSFW somewhere before you guve them your url. Using a link shortener is recommended when posting your url, too.
You would usually get a reply within minutes there.
Also check the indexing status in webmaster tools. If you have less urls indexed, try to figure out why. It is in
Google Index >
Index Status again left sidebar menu in webmaster tools. Check advanced stats and click on
Removed to see, if any urls were removed.
