The present study assessed the gender-specificity of sexual interest of bisexually-identified men and women, compared to gay men and lesbian women. Utilizing viewing time as a measure of sexual interest, self-identified bisexual men (N = 50) and women (N = 54) rated the sexual appeal of sexually provocative pictures while the amount of time spent viewing each picture was inconspicuously measured. As hypothesized, bisexual men and women demonstrated a pattern of sexual interest that was significantly less gender-specific than that of a gay/lesbian sample. That is, bisexual men and women (1) viewed other-sex pictures significantly longer than gay men/lesbian women viewed other-sex pictures and (2) rated other sex pictures significantly more sexually appealing than gay men/lesbians rated other-sex pictures. Additionally, the difference in viewing times and appeal ratings between male and female sexual stimuli for bisexuals was significantly less than the difference evidenced by gay men and lesbians. These findings suggest that self-identified bisexual men and women demonstrate a truly bisexual pattern of sexual interest, characterized by greater other-sex attraction and less gender-specificity than is true for gay men and lesbians.
本研究评估了自我认定为双性恋的男性和女性与男同性恋者和女同性恋者相比,其性兴趣的性别特异性。以观看时间作为性兴趣的衡量标准,自我认定为双性恋的男性(N = 50)和女性(N = 54)对具有性挑逗性的图片的性吸引力进行评分,同时暗中测量观看每张图片所花费的时间。正如所假设的那样,双性恋男性和女性表现出一种性兴趣模式,其性别特异性明显低于男同性恋/女同性恋样本。也就是说,双性恋男性和女性(1)观看异性图片的时间明显长于男同性恋者/女同性恋者观看异性图片的时间,并且(2)对异性图片的性吸引力评分明显高于男同性恋者/女同性恋者对异性图片的评分。此外,双性恋者对男性和女性性刺激的观看时间差异和吸引力评分差异明显小于男同性恋者和女同性恋者所显示的差异。这些发现表明,自我认定为双性恋的男性和女性表现出一种真正的双性恋性兴趣模式,其特征是与男同性恋者和女同性恋者相比,对异性的吸引力更大,性别特异性更低。
