Not every woman who is raped lived through it. That's what's most important. There aren't any easy answers. It comes down to a choice one person made to control another person. Rape isn't a crime about sex.
Sex is only a weapon.
It's even harder if you know the person who raped you. Even if you consented to sex before but didn't this time, it's still rape. You may feel completely betrayed because the person who did this was someone you knew and trusted. That's part of what makes this crime even more awful. No matter how much you trusted this person, the actions taken against you are inexcusable.
