I am referring to domestic cats. My personal research indicates very clearly that during mating when the female struggles or complains the male tries harder and continues beyond the point at which he'd normally have stopped.

You know that the male prevents the female moving away by grasping her by the scruff of the neck in his mouth (as seen in the photo above). It is quite a brutal process. It sort of looks a bit like rape as it includes violence of a sort. The biting of the females neck to keep her compliant and the barbed penis raking her vagina when it is withdrawn. It's not a loving event, let's put it that way!
My cat likes to have sex on my arm when I am wearing an old fleece dressing gown. This is not uncommon. Or this sort of vestigial sex is seen in various forms by male domestic cats and dogs even after neutering. Testosterone is not the only motivator for sex.
But if I move my hand when he is about to stop, he continues. And he will continue as long as I move my hand. He stops eventually but he sees my hand moving and decides that the female he is having sex with is struggling to be free of him. His response is to deny her that release and continue.
If my imaginative interpretation is correct, I am unsure why he does this. It may simply be a process of dominance and the struggle by the female may provoke him to continue. It may even excite him as violence can excite humans during sex.
I am speculating wildly but it is very noticeable so something is happening. It has never been reported before perhaps because it is hardly important.
