Attempted Rape: What to do?

If someone tries to force sexual activity on you, take the following actions recommended by the US Center for Substance Abuse Prevention.  Be aware that the presence of alcohol or other drugs can make the situation more difficult to deal with. Stay calm and think.  Assess your situation quickly. Stay no strongly.  Do not smile.  Do not act friendly or polite.  Say something like, “Stop it.  This is rape.”  It might shock the rapist into stopping.
Look for an escape route.  There is no shame in escaping a dangerous situation.  If you can figure out a way to distract the attacker, you can sometimes run away. Act quickly if possible.  The longer you remain in the situation, the few options you have. Decide if it is safe to resist.  People who hit back and scream have a much  higher chance of cutting short the assault than those who don’t. If the attacker is armed, however, don’t try anything that could bring harm to you.  Some basic steps you might take: Attempt to talk your way out of it.  Appeal to a sense of humanity and decency.  Try to get the attacker to see you as an individual person who is being hurt.
Use passive resistance.  Pretend to faint or thow up. If the attacker is not armed, consider adding some aggressive steps to your plan of action: Use intimidation.  Say that someone is on the way. Shout “fire.”  If you shout “help,” people may ignore you.  They are more likely to respond to “fire.” Fight back.  Try a poke in the eye, a kick, a punch in the Adam’s apple, or a blow with a lamp or other item.  Fight so that you can escape, but resist only as long as it is safe to do so.
