Heterosexual women respond genitally to stimuli featuring both their preferred and nonpreferred genders, whereas men's genital responses are gender-specific, suggesting that gender cues are less relevant to women's sexual response. Instead, prepotent sexual features (exposed and sexually aroused genitals), ubiquitous in audiovisual sexual stimuli, may elicit automatic genital responses, thereby leading to a nonspecific sexual arousal pattern in women. To examine the role of stimulus potency in women's sexual response, we assessed heterosexual women's and men's genital and subjective sexual arousal to slideshows of prepotent stimuli (erect penises and aroused vulvas), non-prepotent stimuli (flaccid penises and female pubic triangles), and sexually neutral stimuli. Contrary to our hypotheses, both women and men demonstrated gender-specific genital and subjective sexual arousal, such that sexual arousal was greatest to prepotent male and female stimuli, respectively. This is the first study to demonstrate gender-specific genital responding in heterosexual women.
异性恋女性对呈现其偏好和非偏好性别的刺激均会产生生殖器反应，而男性的生殖器反应具有性别特异性，这表明性别线索与女性的性反应关联较小。相反，在视听性刺激中普遍存在的优势性特征（外露且性唤起的生殖器）可能引发自动的生殖器反应，从而导致女性出现非特异性的性唤起模式。为了研究刺激强度在女性性反应中的作用，我们评估了异性恋女性和男性对优势刺激（勃起的阴茎和唤起的外阴）、非优势刺激（疲软的阴茎和女性耻骨三角区）以及性中性刺激幻灯片的生殖器和主观性唤起。与我们的假设相反，女性和男性均表现出具有性别特异性的生殖器和主观性唤起，即性唤起分别对优势男性和女性刺激最为强烈。这是第一项证明异性恋女性存在性别特异性生殖器反应的研究。
