Many years ago, I saw a movie about WWII. I don't remember much of it, but I remember a little: A Jewish boy somehow ended up in the Hitlerjugend. When the boys showered together he had to hide his penis as not to show he was circumcised. I think he showered in his underwear. Also he fell in love (or at least got romantically involved) with a German girl who was raised to breed übermenschen. Of course, having sex with her was also a problem because of his circumcision. Can anyone tell me the title of this movie?
