Yes, Mary, that surely happens too. Actually, while I was a JW elder, I was pursued by a female workmate--although not a superior. I was married and so was she, and I was completely shocked at the things she would do and say to me.
She several times approached me, telling me, "I want you!" and "I wanna get naked with you."
Once while I was sitting on a sofa, she sat down between my legs, laid back onto me, picked up my hand and placed it high on her inner thigh. (Geez, I'm getting hot just remembering it.) I didn't go for it. A long time later in my office she told me, exasperated, "I wanted you to f--- me that night, but you wouldn't!"
I don't know how much of this stuff is real or exaggerated. I just know that, while people are certainly sexually targeted in the workplace, the I-Want-You-To-Want-Me fabrications by insecure, ruthless women are also very damaging to many men.
