J/O, of course, is short for jacking off. Nevertheless, when photographer Joe Oppedisa gives his new photo book this title, you shouldn't make the mistake of thinking that the pictures are just jack-o material. Oppedisa's photos of young hunks and beefy men are too cleverly staged for that. Still, it's pretty obvious that these men sweat sex from every pore - and so it's only fair if you use this book as an inspiration for certain moments. Just tell the artist you have our approval.
