[Advice Needed] My Boss Won’t Stop Having s*x With Me! My Job Is At Stake…. Please Help!

Dear Tee,

I have been having issues at work for a while now. At the time I went for the interview for my current job, one of the directors offered to give me the job only if I slept with him. Out of frustration and eagerness to get the job, I agreed and few days later, I was offered a position in the firm. After I resumed work, the director continued to request for s*x which I allowed for a while. Now, I have stopped granting his request to sleep with me, and he has started threatening me and saying I would lose my job. I don’t know what to do. This is my first job since i concluded NYSC four years ago. What should I do? Should I quit my job?
