Date rape and acquaintance rape are forms of sexual assault involving coercive sexual activities perpetrated by an acquaintance of the rape survivor. The perpetrator is almost always a man, and though both men and women can be raped, women are most often the targets of this violence. It is difficult, because of a lack of research on the subject and the tendency for rape survivors not to report attacks, to come up with precise statistics on male survivors.  Date and acquaintance rape can happen to or be perpetrated by anyone. Incidences are very high: they comprise from 80-85% percent of all reported rapes. However, even these figures are not reliable. According to conservative FBI statistics, only 40% of all forms of rape are even reported.Date and acquaintance rape is quite prevalent on campuses. One in four college women has been raped; that is, has been forced, physically or verbally, actively or implicitly, to engage in sexual activity. A 2000 study revealed that 90% of college rape survivors knew their attacker before the incident. The values adopted by the dominant society dictate inherent differences between men and women. Women are expected to be passive, unassertive, and dependent. Similarly, men are constrained in their behavior. They are taught to be aggressive, even intimidating, strong, and relentless. They are taught not to take no for an answer. Men who accept or unwittingly exhibit this kind of behavior are likely to misinterpret a woman's communications. Typically, the man will decide that the woman is acting coy or hard to get in a sexual situation. He may believe that she really means yes, although she has been saying no.Communication is the most important avenue to understanding another person's desires and needs -- often the rapist will ignore the woman's attempts at communication, will misinterpret them and continue his actions.If a person says no and is still coerced or forced into having sex, then a rape has occurred.
