According to this story, the Amora Sex Academy recently opened in Berlin offering hands on displays with somewhat interactive manequins which provide some feedback to touch. If you are able to find the G-spot on one manequin it will shout, "that's it!" And were this not intriguing enough, it also provides many useful facts, for example that the "Italian chandelier" position burns 920 calories an hour. It does not mention, however, how many individuals are able to last an hour. And though the article does not give the specifics of this position, the academy does.
I bring this up because it is a blatant rip off of an idea I had years ago, although there are some minor differences including my much more catchy name - F*^% U. The other primary difference being that my version featured real live prostitutes instead of manequins, with the occasional guest lecture by porn stars. I still think my idea would have been more profitable.
