Knowing the person who raped you can make that assault even harder to bear. But here are places to turn for help. Date rape involves nonconsensual sex between two people who already know each other. Date rape can even occur between two people who have previously had sex. But even if you knew your assailant, if you said no to a sexual act, and it was forced upon you, that is date rape. If you've been raped, do not shower or change. This may be hard, but you'll need to remain as you are in order for evidence to be collected. Call a friend, your local rape crisis center, or your college's health center to report the crime. Then, you'll need to go to the hospital for evidence collection, and to receive STD testing and pregnancy prevention. Note that just because you allow the hospital to collect evidence, or even if you call the police, you do not have to press charges or appear in court. But remember that it is easier to collect evidence now, and change your mind later on, than it is to report a rape without any evidence. After you're through at the hospital, you will be sent home to clean up, rest and recover. Afterwards, it's important to talk to a professional about the impact of the date rape. Even if you decide not to report the crime, receiving this emotional attention and care is a vital step in your recovery process.
