Oh right - yeah of course if there's any victimisation then there's a clear boundary being crossed. But we needn't assume that victimisation is implicit in hate-fucking

It's totally conceivable that it could be entirely a mutual arrangement.
For example, if you really hate your older female boss; you feel she's restricting your career progress and basically frustrates the crap out of you constantly, and then you make a comment one day under your breath and she calls you on it and the dam breaks a bit so all the frustration comes out and unwittingly it's translated as sexual energy for some reason and one thing leads to another... but you still hate each other and intend on keeping it that way afterward

That's totally conceivable.
