Adolf Hitler had a disgusting sexual fetish, according to a top secret spy report.

The Nazi leader’s bedroom habits included a love of “poo sex,” claims a dossier from the US Office of Strategic Services, the forerunner of the Central Intelligence Agency.

The intelligence document says he liked women to stand over him and defecate because he was turned on by poo.

It also revealed the Fuhrer had a “micro penis” and — as the famous song suggests — only one testicle.

It also revealed he liked to be brutally kicked by women as part of his sex games.

The report, by Dr. Walter C. Langer, was commissioned in the Second World War because spy bosses wanted to know what made the evil leader tick.

Langer produced “A Psychological Analysis of Adolph Hitler, His Life and Legend,” which documents the Nazi leader’s hideous sex preferences.
