Reproductive-aged women show increased interest in sexual activity during the fertile phase of the menstrual cycle that can motivate sexual behavior and thereby increase the likelihood of conception. We examined whether women demonstrated greater sexual responses (subjective and genital sexual arousal) to penetrative versus oral sexual activities during the fertile versus non-fertile phases of their cycles, and whether women's arousal responses were influenced by the phase during which they were first exposed to these sexual stimuli (e.g., Slob et al., 1991; Wallen and Rupp, 2010). Twenty-two androphilic women completed two identical sexual arousal assessments in which genital responses were measured with a vaginal photoplethysmograph and their feelings of sexual arousal were recorded. Women viewed an array of 90s films varying by couple type (female-female, male-male, female-male) and sexual activity type (oral or penetrative), during the fertile (follicular) and non-fertile (luteal) phases of their menstrual cycle, with the order of cycle phase at the first testing session counter-balanced. Women tested first in the fertile phase showed significantly greater genital arousal to female-male penetrative versus oral sex in both testing sessions, whereas self-reports of sexual arousal were not affected by cycle phase or testing order. These results contribute to a growing body of research suggesting that fertility status at first exposure to sexual stimuli has a significant effect on subsequent sexual responses to sexual stimuli, and that this effect may differ for subjective versus genital sexual arousal.
生育期女性在月经周期的排卵期表现出对性活动的兴趣增加，这可能会激发性行为，从而增加受孕的可能性。我们研究了女性在周期的排卵期和非排卵期，对插入式和口交式性活动的性反应（主观和生殖器性唤起）是否存在差异，以及女性的唤起反应是否受到首次接触这些性刺激时所处的周期阶段的影响（例如，Slob 等人，1991；Wallen 和 Rupp，2010）。22 名男性偏爱的女性完成了两次完全相同的性唤起评估，使用阴道容积描记法测量生殖器反应，并记录她们的性唤起感。女性在月经周期的排卵期（卵泡期）和非排卵期（黄体期）观看了一系列 90 年代的电影，这些电影的类型因伴侣类型（女-女、男-男、女-男）和性活动类型（口交或插入式）而异，第一次测试时的周期阶段顺序是平衡的。在第一次测试中处于排卵期的女性在两次测试中均表现出对女性-男性插入式性活动的生殖器唤起明显高于口交，而性唤起的自我报告不受周期阶段或测试顺序的影响。这些结果为越来越多的研究提供了支持，表明在首次接触性刺激时的生育状态对随后对性刺激的性反应有显著影响，而这种影响可能在主观和生殖器性唤起方面存在差异。
