I ended up sleeping with my boss
Are you serious? Is sleeping with your boss something you wanted to do?
Yes, I've wanted it for a long time.
It's okay to experience attraction to others. But sleeping with your boss can have negative consequences at work and be potentially unethical. You should end the relationship if both of you will continue to be coworkers.
It's just sex.
It's still a pretty big deal to sleep with your boss. I think you should never do it again unless you want problems at work.
