I linked to the Telegraph article where I learned about the map from because there is a good chance it is a blocked site if you click on it while you are at work. Wouldn't want to get any of you fine folks in trouble with your bosses.
Anyway, here is the address, not even a link, to the actual map. There is no adult content on this page except for some of the search terms. Chances are most work place web filters still block the site so continue at your own discretion.
The page is Pornmd Dot Com/sex-search. Don't blame me if you get yourself in trouble.
