Understanding the processing of sexual stimuli has become a significant part of research on human sexuality. In addition to individual characteristics (gender and sexual orientation), empirical studies have shown that cultural factors play an important role in sexual stimuli processing. The attitudes toward sex have been reported to be more conservative in East Asian societies as compared to western countries, and significantly more sexual difficulties are observed among East Asian people. However, stimulus materials, which potentially facilitate human sexuality research on native East Asian people, are relatively not satisfactory. Erotic stimuli depicting East Asian figures are limited in the existing picture datasets. To address this issue, we present a collection of 237 erotic and 108 control pictures, accompanied by self-reported ratings of sexual arousal, pleasantness, and sexual attractiveness for opposite-sex erotic stimuli by heterosexual males and females ( = 40, divided into two equal-sized subsamples). This collection is divided into six categories, depending on their contents: dressed males (44), semi-nude males (65), nude males (64), dressed females (64), semi-nude females (52), and nude females (56). We showed gender differences in sexual arousal, pleasantness, and sexual attractiveness ratings in response to opposite-sex erotic pictures. Males reported the highest levels of sexual arousal, pleasantness, and sexual attractiveness for nude female pictures, whereas females reported the highest levels of sexual arousal, pleasantness, and sexual attractiveness for semi-nude male pictures. The erotic picture dataset may provide a useful resource of erotic stimuli that can be used as stimulus materials in experimental research on sexual function in East Asians.
理解性刺激的处理过程已成为人类性行为研究的重要组成部分。除了个体特征（性别和性取向）外，实证研究表明文化因素在性刺激处理中也起着重要作用。据报道，与西方国家相比，东亚社会对性的态度更为保守，东亚人群中观察到的性困难也明显更多。然而，对于东亚本土人群的人类性行为研究可能有帮助的刺激材料相对不尽人意。现有图片数据集中描绘东亚人物的色情刺激有限。为了解决这个问题，我们展示了一组237张色情图片和108张对照图片，并附有异性恋男性和女性对异性色情刺激的性唤起、愉悦感和性吸引力的自我报告评分（ = 40，分为两个等规模的子样本）。这个集合根据内容分为六类：穿着衣服的男性（44张）、半裸男性（65张）、裸体男性（64张）、穿着衣服的女性（64张）、半裸女性（52张）和裸体女性（56张）。我们展示了在对异性色情图片的性唤起、愉悦感和性吸引力评分上的性别差异。男性对裸体女性图片的性唤起、愉悦感和性吸引力评分最高，而女性对半裸男性图片的性唤起、愉悦感和性吸引力评分最高。该色情图片数据集可能为色情刺激提供一个有用的资源，可作为东亚人性功能实验研究中的刺激材料。
