We just started reading the new book Bonk by Mary Roach. So far, we dig it. We'll post soon with a full book report. In the meantime, check out Slate's video-interview with her, in which she discusses doing it with her husband under the microscope, as it were, in the name of science. They've actually got clips of it! But before you pop a tent in your pants, consider you pervs warned: it's about as arousing as an 7th grade abstinence-only sex ed class. Then again, we're sure there are at least a couple of 4-D ultrasound fetishists out there.
