Perhaps you know a woman who is a victim of sexual assault. Listen to her. Tell her it was not her fault and that she is not alone. Find out where she can get support in your area and tell her about it. Give her this pamphlet.
Every woman suffers and is traumatized by a sexual assault, even several years later.
She may show this in various ways, or not at all. It would be best for you to talk to someone about it. If you want a criminal investigation, you must tell the police that you were the victim of a sexual assault. A medical examination may be necessary. In that case, it must be carried out as soon as possible after the assault.
