Double X

The photographer Joe Oppedisano has just released a sexy new book called "Testosterone" From the look of things, the collection seems to capture men -- and their signature hormone -- in all of their hard, wild and aggressive glory.

Lots of skin, sweat, leather and dirt will undoubtedly get your juices flowing, and the setting of most of the photos -- in gloomy places like bars, cellars and stairwells -- will leave you feeling like you've just spent the weekend in a tina hole at the Lure. (Talk about the perfect Christmas gift.)
