Author Mary Roach just finished a book tour for Bonk: The Curious Coupling of Science and Sex, in which she explores the world of sex research both as an observer and a participant. In one strange episode, she and her husband fuck on cue for a sex researcher; in another, she watches porn with a probe in her hoo-ha to measure her arousal (I did that in college for $125!). Other interesting tidbits: chimps have orgasms; Alfred Kinsey stuck a toothbrush in his urethra while masturbating; and the San Francisco Fire Department has a cock ring emergency response unit. I think we all know what book your editors will be passing around when one of us finishes translating Wetlands. [ABC News]
