This study evaluated the rape fantasies of female undergraduates (N = 355) using a fantasy checklist that reflected the legal definition of rape and a sexual fantasy log that included systematic prompts and self-ratings. Results indicated that 62% of women have had a rape fantasy, which is somewhat higher than previous estimates. For women who have had rape fantasies, the median frequency of these fantasies was about 4 times per year, with 14% of participants reporting that they had rape fantasies at least once a week. In contrast to previous research, which suggested that rape fantasies were either entirely aversive or entirely erotic, rape fantasies were found to exist on an erotic-aversive continuum, with 9% completely aversive, 45% completely erotic, and 46% both erotic and aversive.

Additional research and clinical reports suggest that four to five percent of women have reported orgasm during sexual assault, but the numbers could be higher
