Why is my boss doing this?? I am a 27 season old woman who functions for a big business 
business. My boss who's 42 years outdated, simply asked me about my sexual orientation if I’m straight or not, 
and then he asked me “was your ex partner sexually aggressive with you?” 
I was so uncomfortable Furthermore, he stares at me at the corner of his 
eyesight and i... display more  He's acting like 
that because you allow it.  He gets his thrills viewing you squirm.
The next time, at work, tell him to "buzz off".  Then walk away and "totally ignore" all the staring,
stupid questions, etc.  Don't answer him and don't show him that it bothers you.

Simply ignore him.
