book I read

in the mid to late 70's (highshool) I read a book where a man was mentally tortured by his youth where during ww2 he spent it as a boy in a jewish boy whore house. There was no sex described in the book. There was a scene where a ss officer had a boy dress as hitler and play with trains and toy soldiers. I could not of imagined a story of this nature but it escapes me the title sorry for this non site related blog but I can't get this book out of my head. So anybody else remember this
thanks
