I'm in my mid 20's and so is my coworker. Anyway, this morning my coworker left his laptop alone in his desk and I started browsing his recent browser history out of curiosity. I found many links to adult pages and most of them had underage little girls completely naked. I don't know what to think, I could've never imagined him doing such a thing. I'm having a serious mental breakdown over this; he's a very attractive and fit guy and not at all the kind of guy you would expect to have such habits. Maybe it was a friend of his using his computer? At first I thought about reporting him to the authorities, but it would not be a good decision since at my workplace we run a really close-knit group and everyone has a great vibe (mostly men) and such a thing would destroy the group and probably my relationships with bosses and coworkers
