Consensual Victim-Perpetrator Intercourse after Nonconsensual Sex: The Impact of Prior Relationship

Some female victims of nonconsensual sex subsequently have consensual sexual intercourse with the perpetrator and are more likely to do so if intercourse occurred during the nonconsensual sex than if it did not. Some evolutionary psychologists have postulated that there is something significant about nonconsensual intercourse that causes women to subsequently have a sexual relationship with the perpetrator (e.g., risk of pregnancy). In this study, we investigated a parsimonious explanation that has previously been overlooked: Intercourse is more likely during nonconsensual sex when the victim and perpetrator have previously had a sexual relationship; thus, subsequent consensual intercourse may simply be a continuation of that prior relationship. A sample of 945 women completed an Internet-based survey, of whom 41% had experienced nonconsensual sex since age 14. As expected, victims who had intercourse with perpetrators prior to the nonconsensual sex event were significantly more likely than other victims to experience nonconsensual intercourse and to engage in subsequent consensual intercourse with the perpetrator. When considering only the small subsample of victims who never had a prior romantic or sexual relationship with the perpetrator, the odds of subsequent consensual intercourse were still significantly greater following nonconsensual sex with intercourse versus without intercourse.
