It's simple really. Women are basically genetically programmed to enjoy rape (not saying it's right).

From an evolutionary biology stadnpoint, our hips became narrower during the transition to bipedalism and our craniums widened along with the increased intelligence. These two combined meant that childbirth was especially difficult for females of our species and complications during childbirth were the cause of a high mortality rate for much of human history. This is why our babies have to be born tiny and premature and childbirth is painful compared to every other mammal on this planet.

Because childbirth is so costly human females developed an overly stringent standard for their mates and as a result 90% of males can not live up to that standard and rape became the predominant strategy for reproduction.
Females that could not be aroused by rape (ie provide vaginal lubrication) would be injured in the process and often died from infections or from trying to abort the rapist's child. Most of the women alive today are the result of a natural selection process that favors rape fetishization.
