It has been proposed that acute pain can generally be reduced by sexual activity. Increasing subjective sexual arousal might thus help reduce pain during sex. Yet, in conflict with the view that subjective sexual arousal would generally reduce pain, previous research has failed to find that presenting a sexually arousing film stimulus attenuates pain during a cold pressor test (CPT) in women. This might be due to the sexually arousing film having also elicited disgust. Therefore, this study tested whether subjective sexual arousal could generally reduce pain, provided that concurrently-elicited disgust is minimized. Female undergraduates with no sexual dysfunction were randomly distributed through a digital list randomizer to either watch: a porn film that can elicit similar levels of disgust and sexual arousal, a porn film that elicits greater subjective sexual arousal than disgust, or a neutral train ride film (N = 174). A CPT was utilized for pain induction while simultaneously viewing the assigned films. Pain was indexed by subjective ratings of pain intensity, and CPT duration. The results showed no differences in pain intensity or pain tolerance across conditions. Thus, in this study, disgust appeared no critical moderator of the relationship between sexual arousal and pain. The findings converge to the conclusion that, in women, subjective sexual arousal does not generally reduce the experience of pain. This might also imply that increasing subjective sexual arousal alone might not be sufficient to reduce genital pain, though further research is needed to test this inference given that pain sensitivities may differ across the body.
有人提出,急性疼痛通常可以通过性活动来减轻。因此,增加主观性唤起可能有助于减轻性行为中的疼痛。然而,与主观性唤起通常会减轻疼痛的观点相矛盾的是,先前的研究未能发现呈现性唤起的电影刺激会减轻女性冷加压试验(CPT)期间的疼痛。这可能是因为性唤起的电影也引发了厌恶感。因此,本研究测试了在同时引发的厌恶感最小化的情况下,主观性唤起是否通常可以减轻疼痛。没有性功能障碍的女大学生通过数字列表随机化器随机分配,分别观看:一部能引发相似程度厌恶感和性唤起的色情电影、一部引发的主观性唤起大于厌恶感的色情电影,或一部中性的火车旅行电影(N = 174)。在观看指定电影的同时,使用CPT诱导疼痛。通过疼痛强度的主观评分和CPT持续时间来衡量疼痛。结果显示,不同条件下的疼痛强度或疼痛耐受性没有差异。因此,在本研究中,厌恶感似乎不是性唤起与疼痛之间关系的关键调节因素。这些发现得出的结论是,在女性中,主观性唤起通常不会减轻疼痛体验。这也可能意味着,仅增加主观性唤起可能不足以减轻生殖器疼痛,不过鉴于身体不同部位的疼痛敏感性可能不同,需要进一步研究来验证这一推断。
