[[NSFW]]! Should I feel violated? What should I do?

A boy in the senior class talked to me today. I’ve never really noticed him B4, but I do know he’s been in a lot of therapy. I just didn’t know for what till now. He had a confession to make. He struggles with intense sexual fantasies, like rape and stuff. His special fantasy is me, in a bad way. He said his therapist had told him to write stories of his fantasies with me to “help ease the need.” I thought he was lying. So I talked to his therapist, at school…and he wasn’t.

I feel violated and creeped out. I don’t want to admit to myself that this boy I barly know is writing violent sexual stories with me as the star. Do I have to tolerate this? What should I do?
