Sounds fun, but sex with co workers causes drama. I have never done it, but friends have been fired for it. I saw a guy like me get promoted, first week he was fuckin one of his sales reps. She got pregnant, his real girl hit the fan. Managment found out and all of them got fired.
Not sure where you work, but if it is your career, lay back and chill. If you work at burger king or the food court at the local mall, you should probably be nailin that bitch in the restroom.
