Abstract：
We explored the unique roles that body and genital image play in behavior-specific orgasm consistency, beyond overall sexual self-esteem. US adults (N = 599; 64% women) completed questionnaires online. Hierarchical regression analyses predicted orgasm consistency during receptive oral sex and penile-vaginal intercourse (PVI) with additional clitoral stimulation (WAS) and with no additional clitoral stimulation (NAS) for the woman. Body image, genital image, and gender were entered in later steps to assess model improvement above sexual self-esteem. Models accounted for age, sexual and racial minority identities, and current relationship status. Results indicated that genital image improved all models and predicted higher orgasm consistency across all behaviors for men and women. For orgasm during receptive oral sex and PVI-NAS, sexual self-esteem was no longer significant once genital image was included. Genital image was a stronger predictor of women\'s versus men\'s orgasm during PVI-NAS; no significant gender differences were found for oral sex and PVI-WAS. Body image was not significant in any models, contrary to expectations, suggesting role overlap with sexual self-esteem. Genital image appears to play a unique role in sexual pleasure beyond overall sexual self-esteem and body image.
摘要：
我们探索了身体和生殖器形象在行为特异性性高潮一致性中的独特作用，超越整体的性自尊。美国成年人（N=599；64％的女性）在网上完成了问卷调查。分层回归分析预测了接受性口交和阴茎-阴道性交（PVI）期间的性高潮一致性，并带有额外的阴蒂刺激（WAS），而没有额外的阴蒂刺激（NAS）。身体图像,生殖器形象，在随后的步骤中输入性别，以评估高于性自尊的模型改善。模型占年龄，性和种族少数身份，和当前的关系状态。结果表明，生殖器图像改善了所有模型，并预测了男性和女性所有行为的性高潮一致性。对于接受性口交和PVI-NAS期间的性高潮，一旦包括生殖器图像，性自尊不再显著。在PVI-NAS期间，生殖器形象是女性性高潮与男性性高潮的更强预测指标；在口交和PVI-WAS中没有发现明显的性别差异。身体图像在任何模型中都不显著，与预期相反,暗示角色与性自尊重叠。生殖器形象似乎在性快感方面发挥着独特的作用，超越了整体的性自尊和身体形象。
