I believe a female colleague saw me masturbating at work. I was in my office after hours with the door locked and blinds down, but I'm afraid the blinds had a crack. I am not an exhibitionist, and this was a moment of weakness. This incident would have been over a month ago, and yes, I have stopped doing that. I only work with my door and blinds open now.
She's been glaring at me for weeks with what looks like contempt. Sometimes I won't even know she's there, but I turn to see her staring me down. It's incredibly uncomfortable.
I have not approached her, and it has never been acknowledged that this is why she's upset. Actually, I'm not even 100% sure if she saw me, but I cannot explain the behavior otherwise, as our rapport went from positive to suddenly hostile without any explanation. I once went to her cubicle and she immediately told me my presence was unwanted. She has had a history of reporting male colleagues that have unwanted advances on her, so I'm afraid that whatever I do to rectify the scenario will make it worse. I don't generally spend time around this person, so I can't think what else I could have done to offend.
How should I approach this scenario? It could be that she's mad about something entirely different, but I wouldn't have the slightest idea at what.
This is in a midwestern US company with roughly 200 employees. We're not in the same unit, but at times are at the same meetings. Nobody else seems to be treating me differently, and I am generally very well-liked by my other colleagues.
