All I know is it sounds British. We just don't use the word wank here in the states; We do it, but we just call it something else. And I certainly wouldn't advise using a fan; It sounds pretty painful, and if your not careful, you'll only be able to do it once. If you absolutely positively have to experiment, try vacuumwanking; Only remember to take the rotating powered part off of the hose first, otherwise you may as well be fanwanking.
