Greater vibrotactile sensitivity has been related to better erectile function in men, and vibrotactile and pressure tactile sensitivity have been related to better sexual function in women. Our previous study found that, for both sexes, greater recalled body awareness during last sexual relation correlated with greater recalled desire and arousal. Using the same sample of that study (68 women and 48 men, recruited in the Lisbon area, Portugal), we tested if greater recalled body awareness during last sexual relation correlates with tactile pressure sensitivity, as assessed by von Frey microfilaments. In simple and partial correlations controlling for social desirability and smoking before last sex, the hypothesis was confirmed for women, but not for men. Greater tactile sensitivity might enhance sexual arousal through greater awareness of the body during sex, and/or more frequent and pleasant body sensations during sex might lead to greater tactile sensitivity in nonsexual situations. Pressure sensitivity might be more closely linked to sexual arousal in women than in men.
男性较高的振动触觉敏感性与更好的勃起功能有关，而振动触觉和压力触觉敏感性与女性更好的性功能有关。我们之前的研究发现，对于男女两性而言，上次性行为中更高的身体觉知与更高的性欲望和性唤起相关。使用该研究的同一组样本（在葡萄牙里斯本地区招募的68名女性和48名男性），我们测试了上次性行为中更高的身体觉知是否与通过von Frey微丝评估的触觉压力敏感性相关。在控制了社会期望和上次性行为前吸烟情况的简单和偏相关分析中，该假设在女性中得到证实，但在男性中未得到证实。更高的触觉敏感性可能通过性行为中对身体的更高觉知来增强性唤起，和/或性行为中更频繁和愉悦的身体感觉可能导致非性情境下更高的触觉敏感性。压力敏感性在女性中可能比在男性中与性唤起联系更紧密。
