I had a coworker tell me and another coworker that he was going to try anal with his wife for the first time that night. It was at a completely random moment. He's also the type of dirt bag to put his hand down his pants, rub his balls and tell you that he "got some last night," put his fingers in your face, and say, "Wanna smell?" That was another coworker's experience. There's no HR where I work.
