The Facts About Sexual Assault

Some people have the wrong idea about sexual assault and rape. They think the attacker was overcome with sexual desire, the victim was dressed too seductively, or the victim asked for it. These ideas assume that sexual assault is motivated by sexual desire. It isn't. It’s a violent crime, a hostile attack, an attempt to hurt, humiliate, and control the victim. Sex is only the weapon. 

Sexual assault is the sexual abuse, fondling, and/or touching of a person in areas of the body considered private, against her or his will, by force, threats, and/or intimidation.

Rape is sexual intercourse with a person against her/his will through force, threats, and/or intimidation. Remember that there is a different between consent and submission out of fear. If you fear for your life, your physical safety, or thief and safety of a loved one, you may sincerely believe you have no other alternative than to submit to a sexual act. This does not mean that you have consented to it; submission is not consent. The decision to resist or not to resist can only be made by the person who is attacked.

The Victim/Survivor - You are a victim of a crime if you have had unwanted sexual contact. Sexual assault is no less serious if you know your assailant. Previous sexual contact with your assailant does not justify or excuse the crime. If you think sexual assault is motivated by passion or happens because the victim asked for or wanted it, look at the facts. Sexual assault can happen to anyone, you your children, co-workers, or friends, or other members of your family.

The Situation - Perhaps you think sexual assault happens only in certain high-risk situations such as hitchhiking, walking alone at night, or going out socially alone. It's true that sexual assault can occur in such situations but it also takes place in ordinary, seemingly safe places. In fact, about one-third of all rapes occur in or near the victim's residence. About one-half of the rapes are by first or causal dates or romantic acquaintances.

The Assailant - It is important to be aware that most sexual offenders don't look abnormal or act strangely. In fact, perpetrators of rape and sexual assault are not always stranger to their victims. In many cases, the assailant is an acquaintance, neighbor, friend or relative.

The Crime - I thought I could trust him; I thought he was my friend, I started feeling uncomfortable, but I ignored my feelings. I thought he would never do anything to hurt me. Suddenly, he was a stranger. He was doing something I never thought he would be capable of -my friend was raping me. --Sarah-20-year old acquaintance and rape survivor.
