Adolph Hitler’s third secret is out. At it’s one dirty secret because it involves faeces.

The dossier from the US Office of Strategic Services, which preceded the CIA, has an intelligence report that says the German dictator loves poo sex. Because he was turned on by human excrement, Hitler had women stand over him and defecate, reports the New York Post.

The Fuhrer was also apparently into sado-masochistic sex as he enjoys being kicked hard by women as part of their sex play, the report adds. The revelation is on the heels of a report in December that the German leader only had one testicle because of a birth defect, although Hitler claimed it was the result of a World War I shrapnel hit.

On top of that, he had a micro penis. These pieces of embarrassing information were part of a report by Dr Walter C. Langer who was commissioned during World War II to know what were the things that turned on the dictator. The sex preferences of Hitler were all discussed in Langer’s report titled “A Psychological Analysis of Adolph Hitler, His Life and Legend.”

In the report, Langer concluded that Hitler was incapable of normal sex. His condition is known as coprophilia which the Medical Dictionary defines as “an absorbing interest in feces or filth, particularly a paraphilia in which sexual arousal or activity is linked to feces.”

The report says Hitler’s niece, Geli Raubal, was the one who indulged in the act that Langer wrote as a perversion that “represents the lowest depths of degradation.” Raubal allegedly shared the information with Otto Strasser, a Nazi supporter who eventually left the regime. Her narrative was corroborated by another Nazi, Ernst Roehm, who talked about Hitler’s fetish which spies picked up.

The woman who was forced to kick Hitler while he lay on the floor was Renate Muller, a German actress who later took her own life.
