Amethyst is right. You feel pressured to talk with her about it. You’re a victim. You need to report it. It IS sexual harassment. Someone who wants to go on and on about weird sexual details surrounding their own parents can be a really dangerous person to be around. She could be testing the waters to go further and further before she wants you to watch some kind of weird incest p*rn or even try to SA you because she clearly doesn’t understand boundaries or normal sexual thoughts/behaviors.
There is no gentleness in this. I would feel unsafe around this person. Someone like this doesn’t know what’s sexually appropriate. That’s scary. That’s not a safe environment to live in, and quite frankly, getting the roommate therapy is not their responsibility. I know that sounds rough but the objective should be for them to put their safety first and get away from the person who thinks talking about their mother’s vagina and how much their dad loves it 24/7 is normal. They need out.
I understand where your thought process is and what you think may have happened to this roommate growing up, hence the speculation of needing a therapist. My first roommate (before I moved out) was sexually ab*used as a child and TOLD ME stories about it. The problem was, she had no idea it was sexual ab*use, even as an adult. I know it’s sad and no one should ever have to go through that but that’s not OP’s fault and I know from experience that it’s extremely uncomfortable to live with.
