One campus women's liaison at a major university was told by members of a fraternity that they assume that women who immediately approach the bar upon arrival are there for sex, regardless of the possibility that some women may feel insecure or shy. Naivete, poor judgment, shyness, even reckless behavior is not a crime. Sexual assault is the only crime where the relationship between the parties is deemed relevant and the victim's prior behavior is considered provocation. Women give mixed messages because they don't want to admit that they really want to have sex. They just need to be convinced, to relax and enjoy themselves.
Rape is violence using sex as a weapon.
Survivors of sexual violence feel very clearly that rape and consensual sex are worlds apart. It can even involve threats, sometimes against the women's life, or her livelihood, or academic career, or even family members or friends. Many survivors recall being in fear of their lives, even if a weapon was not present. In Los Angeles, rape hotline calls revealed the average length of a rape was 3.5 hours. A rapist is easy to spot in a crowd.
