Considering the overwhelming amount of cases where males are the liars, the law will never change its bias on this subject matter, so men will have to deal with it by being careful. Condoms should be required with hookups anyways considering current STD statistics. Finally, women typically do not have the muscle strength to stop a man from ejaculating in them during a last moment decision.

I agree that the law can be bullshit at times, but generally it is for the common welfare of women who are taken advantage of by males who's sex drive is naturally more aggressive.
