Mary Roach's TED Talk, "10 things you didn't know about orgasm," will have you scratching your, um, head, in amazement as you learn the particulars of pig-wanking, the delicate matter of explaining foreplay to royalty, and the business of measuring the human penis's muzzle-velocity.
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.
