Men's genital arousal occurs in response to a limited number of sexual stimuli, whereas women's genital arousal occurs in response to a wide range of sexual stimuli, including those depicting nonpreferred cues. Researchers have hypothesized that women's nonspecific pattern of genital arousal prepares the body for sexual activity, thus functioning to protect the genital organs against injury. If this hypothesis is correct, women should show genital responses to any cues suggesting sexual activity, even unappealing cues that involve nonconsensual sex and extreme violence. Fifteen men and 15 women listened to fourteen 2-min audiotaped narratives that depicted an interaction between a man and a woman and that varied factorially according to the presence of consent, violence, and sexual activity. The results support the preparation hypothesis: Men showed the greatest genital arousal in response to narratives depicting consensual, nonviolent sex, whereas women showed similar responses to all the narratives involving sexual activities, including those describing a sexual assault.
男性生殖器的兴奋是对有限数量的性刺激的反应，而女性生殖器的兴奋是对广泛的性刺激的反应，包括那些描绘非偏好线索的刺激。研究人员假设，女性非特定模式的生殖器兴奋为性行为做好了身体准备，从而起到保护生殖器器官免受伤害的作用。如果这个假设是正确的，那么女性应该对任何暗示性行为的线索做出生殖器反应，即使是不吸引人的线索，涉及非自愿的性行为和极端暴力。15 名男性和 15 名女性听了 14 个 2 分钟的录音叙述，这些叙述描绘了一个男人和一个女人之间的互动，根据同意、暴力和性活动的存在，这些叙述以因子的方式变化。结果支持准备假说：男性对描述同意、非暴力性行为的叙述表现出最大的生殖器兴奋，而女性对所有涉及性活动的叙述表现出相似的反应，包括描述性侵犯的叙述。
