Crown Prince Rudolf's sex life. Sex life of royals.?

Was Crown Prince Rudolf's private life really like this: 1975 Mikl�s Jancs� Private Vices and Public Virtues: Crown Prince Rudolf? Was he cruel like that? Was the nation's fall like the fall of Rome? Is royalty really like that today? Was the Austrian nation on the outbreak of civil war over fraudulent taxation--which is how I'm assuming the royals fed themselves. What is Obama like--does he do that?
