My friend is lesbian. Apparently, her faculty adviser found this fascinating. During their regular meetings, instead of keeping to the purpose of their meetings (ie. her research), he would do things like ask whether she found particular women attractive or not. He also repeatedly commented that she would be more attractive it she wore more feminine clothing, or wore her hair differently (ie. past her shoulders). According to her, these kinds of inappropriate digressions happened regularly. She not only felt objectified and creeped out by his behavior, but the digressions took substantial time away from making progress with her research. Sometimes, she could not proceed further in her work without his input, and he would spend their whole meeting on stuff like that. Keep in mind, she's a student, racking up loans while getting her degree, so these kinds of frequent delays were costing her money as well as time, aside from the whole issue of harassment.
I don't know why she would make this stuff up. She's not an attention seeker, and obviously doesn't intend to seek retribution or punishment against the guy. She's quiet, introverted, and non-confrontational.
Furthermore, I have a male friend who had the same faculty adviser. The adviser was a total asshole to him. He regularly implied or directly called my male friend an idiot. Again, my male friend is quiet, introverted, and non-confrontational, so he got walked on. I'm not sure how much of a difference it would have made if he weren't, though, due to the power dynamic. I attended his defense, and actually met the adviser. There were five professors at his defense, including his adviser. Among these, only his adviser interrupted his defense to criticize his presentation. Frequently, and usually for something completely trivial. Several times, he insisted that my friend change the phrasing of a statement, to the point where he would literally tell him exactly what to say, then have him repeat it out loud, word for word. It was embarrassingly obvious to everyone in the room that this adviser just loved the power, and loved to exercise it in ways that would trivialize or demean others. It was absurd to watch, even if it weren't my friend taking the brunt of the abuse.
