How far into a rape does a woman finally give consent? Depends on the time of death, really.
Are you sure that we should be making jokes about raping women?
I'm not sure about you but for me if she doesn't scream or say she doesn't want the guy she's asking for it.
Rape is such a personal attack on a person that you shouldn't want women to go through it. You wouldn't want to be rape by another person just because of your sex.
Do you have a statistics on how many times women have actually wanted to have sex with a man but then changed their minds?
I do not have any of these stats, but that does not matter. No means no. They are allowed to change their mind at any time.
