It occurred to me today that I actually did know someone who later made a false rape accusation against a guy she’d had consensual sex with. I’d forgotten about this because it happened years and years ago, the woman was someone I’d been in elementary school with and hadn’t seen since, and I only heard the story secondhand. It isn’t a case of “next morning regrets”, but I think it’s close enough to what the OP was looking for.
A little backstory: “Theresa” was a friend of my friend “Susan” in elementary school. Susan and I continued on to the public middle school, but Theresa went on to the local private Catholic school. I then moved away and never saw Theresa again. But I remained in touch with Susan, and when we were about 17 she told me the following story on the phone.
Theresa was caught having sex with a black classmate (his race will be important later) in the school library. She initially claimed that he had raped her, but her story soon fell apart. What had actually happened was that Theresa had in the years since I’d known her developed a drug problem and had made an agreement with this guy to exchange sex for pills.
I don’t know any more details than that, and I never heard what happened to either of them afterward. I don’t know how long it took for Theresa to admit the truth. Susan didn’t mention the police being involved, but they may have been.
Theresa’s motivations for lying are obvious enough: she was trying to cover her own ass. Aside from whatever punishment she’d have faced for having sex in the school library, her parents were also very strict and her father in particular was both overbearing and openly racist. I remember young Theresa saying quite casually that the reason she was changing to the private school was because her father didn’t want her at the public middle school where there were “too many black people”. I suspect her parents would have been angry that Theresa was having pre-martial sex at all, and her father would definitely have been angry that she was getting it on with a black guy. So Theresa tried to throw the guy under the bus to protect herself. She’d be the innocent victim, not the pill-popping slut.
I suspect everyone’s first reaction to this story is the same as mine when I heard it: “Wow, what a bitch.”
The guy involved absolutely did not deserve to be accused of rape, and Theresa’s decision to tell that lie about him was 100% HER fault. But if he’d exercised better judgment, as I’ve repeatedly suggested here, he could easily have avoided the whole ugly situation. He could have stopped and said to himself, “Maybe it’s not really such a good idea for me, a young black man living in the South, to have sex with a white girl with a racist father right here in the school library, especially since she is only agreeing to have sex with me because she’s a pill-popper who needs a fix.”
