I woke Up to Find Myself With My MD on Bed - Female Staff Cries Out, Seeks Advice

This is really a shocking news. The female staff speaks up:

I am a P.A. to the Managing Director of a big company and whenever we have the Annual General Meeting, we often book rooms into the venue of such meetings for effective co-ordination. A few weeks ago, we had last year’s AGM and a few of us got a bit drunk as the meeting went rather well.

My boss has been flirting with me for months even though I told him I wasn’t interested. You can imagine how shocked I was when I woke up the next morning to find my boss in my bed!
I don’t know if anything happened between us as he looked really smashed too and I still had some clothes on. I’m currently on leave and I’m terrified of going back to work as I have developed an itchy discharge. How can I convince my boss I’m not interested in him s*xually and let him know I might have infected him? My job is on the line here! I need your help.

 

Please kindly advice this lady.
