As an employer and someone who knows how energy works, I would never make it a rule do not have sex with a coworker, because that’s going to happen regardless of rules. I can however make it a rule to have your emotional body under control during all your interactions with coworkers so there is never a conflict that takes away from the work. If you do, then you need to learn how the emotional body works and how to keep control over it.  If you can’t keep it in your pants, keep it in your heart and keep it courteous and respectful or keep it out of my business.  Given time, almost everyone is going to have sex with almost everyone else, so don’t waste anyone’s time legislating that. But if you can’t keep your emotions under control and maintain mindful focus enough to handle yourself professionally in a business environment, I love ya but you’re fired.
