This 1943 Amazing Stories ad for an anally inserted vibrator "to treat prostatitis" is the male equivalent of those coded ads for phallic "neck massagers" that ran around the same time and later, gracing the pages of the Sears Catalog and others.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
