Just because a woman doesn't scream doesnt mean she wasn't raped. There is date rape, sex with those who cannot consent, and injury or death threats for example. It is reasonable to assume that men would want the victim to be quiet. He doesn't want to be found. If a woman agrees to be raped, it can still be rape because it was unwanted. For guys who do not understand this, it may make more sense if you imagine yourself dealing with a guy rapist.
