It happens a lot in fiction. I don't know if it exists irl. Probably not.
But feel free to prove me wrong: if you have stories about your own hatesex experiences and want to share with the group, by all means go ahead!
Oh, it happens in real life, too.
Had a couple of co-workers at a restaurant I worked at years ago who were like this. He thought she was an uptight bitch. She thought he was a rude dick. And neither one was shy about letting the other one (and everybody else in earshot) know. Constantly sniping and snarking at one another. The one I remember was when she was complaining about what a fuck-up he was as a waiter, and he told her it was a good thing she was pretty because she was fucking worthless for anything else. She waited until the end of the night after all the customers had left and dumped a whole pitcher of iced tea on his head.
But then we'd have the occasional party after work, or we'd all go to a bar. And once they had enough liquor in 'em, they'd wind up in a private corner somewhere having a snog. And then they'd go to his place or her place and grudgefuck each other's brains out.
This happened, oh, four or five times. And the acrimony between them never thawed. In fact, after the second time, the guy said he would piss her off on purpose because he thought it made the sex better.
And then he quit and got a job somewhere else out of the restaurant business, and that was the end of that.
Sometimes physical attractiveness and raw animal magnetism can overcome a wide variety of personality sins.
