Michelle Issadore, Campus sexual assault expert
I wholeheartedly second Dr. Clemens' answer and would also encourage you to document some instances and examples, in detail. This would include the exhibited behavior, its impact on you, the date, witnessed interactions with heterosexual-identifying/heterosexual-presenting peers and how they may differ from your own, etc. Such a record will perhaps demonstrate a pattern of hostile behavior, should you decide to move forward with a harassment complaint. Even if you choose to address the issue more informally directly with your professor, it will give her an idea of what you have been experiencing and what actions she may be able to adjust in the future to be more accepting.
