Mostly heterosexual men describe themselves as slightly bisexual, with predominant sexual attraction to women but occasional attraction to men. After "completely heterosexual," "mostly heterosexual" is the most common male sexual orientation, by self-report. However, self-reported bisexual feelings among men can diverge from patterns of genital arousal, an objective measure of sexual interest with high validity. We compared 49 mostly heterosexual and 50 completely heterosexual men's patterns of genital and subjective sexual arousal to male and female erotic stimuli. In addition, we compared these groups on relevant self-report measures pertaining to sexual feelings, identity, and behavior. Results supported increased bisexual arousal with respect to self-report and genital arousal pattern among the mostly heterosexual men, compared with the completely heterosexual men. Furthermore, mostly heterosexual men reported more childhood gender nonconformity, greater male sex partners, and less self-reported disgust or aversion to sex acts with men. "Mostly heterosexual" appears to be a gradation of male sexual orientation associated with unique genital arousal patterns, among other correlates.
大多数异性恋男性形容自己为轻度双性恋者，他们主要对女性有性吸引力，但偶尔也会对男性有吸引力。在“完全异性恋”之后，“大多数异性恋”是最常见的男性性取向，这是自我报告的结果。然而，男性自我报告的双性恋感受可能与生殖器唤起的模式不同，生殖器唤起是一种具有高度有效性的客观衡量性兴趣的指标。我们比较了 49 名大多数异性恋男性和 50 名完全异性恋男性对男性和女性色情刺激的生殖器和主观性唤起模式。此外，我们还比较了这些群体在与性感受、身份和行为相关的自我报告测量上的差异。结果支持大多数异性恋男性与完全异性恋男性相比，在自我报告和生殖器唤起模式上表现出更多的双性恋唤起。此外，大多数异性恋男性报告说他们在童年时期的性别表现更为不一致，有更多的男性性伴侣，对与男性发生性行为的厌恶或反感程度较低。“大多数异性恋”似乎是一种与独特的生殖器唤起模式相关的男性性取向的渐变，还有其他相关因素。
