Sex is not an implied payback for dinner or other expense, no matter how much money has been spent. Acquaintance rape is committed by men who are easy to identify as rapists. Victims who don't fight back haven't been raped. Intimate kissing or certain kinds of touching mean that intercourse is inevitable. Once a man reaches a certain point of arousal, sex is inevitable, and he can't help forcing himself on a woman.
Men are capable of exercising restraint in acting upon sexual urges.
Most people lie about acquaintance rape because they have regrets after consensual sex. This belief is based on rigid, outdated sexual stereotypes. Certain behaviors such as drinking or dressing in a sexually appealing way make rape the victim's responsibility. Drinking or dressing in a sexually appealing way are not invitations for sex. Take steps to ensure that schools and other organizations promote violence-free environments.
