Women's preferences for penis size may affect men's comfort with their own bodies and may have implications for sexual health. Studies of women's penis size preferences typically have relied on their abstract ratings or selecting amongst 2D, flaccid images. This study used haptic stimuli to allow assessment of women's size recall accuracy for the first time, as well as examine their preferences for erect penis sizes in different relationship contexts. Women (N = 75) selected amongst 33, 3D models. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference. Women preferred a penis of slightly larger circumference and length for one-time (length = 6.4 inches/16.3 cm, circumference = 5.0 inches/12.7 cm) versus long-term (length = 6.3 inches/16.0 cm, circumference = 4.8 inches/12.2 cm) sexual partners. These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average.
女性对阴茎大小的偏好可能会影响男性对自身身体的舒适度，并且可能对性健康产生影响。关于女性对阴茎大小偏好的研究通常依赖于她们的抽象评分或在二维、疲软图像中进行选择。本研究首次使用触觉刺激来评估女性对尺寸的回忆准确性，并考察她们在不同关系背景下对勃起阴茎大小的偏好。75名女性从33个三维模型中进行选择。使用这种方法，女性能够准确回忆模型尺寸，不过她们在阴茎长度方面比周长方面犯的错误更多。与长期性伴侣相比，女性更喜欢一次性伴侣的阴茎周长和长度略大一些（长度=6.4英寸/16.3厘米，周长=5.0英寸/12.7厘米），而长期伴侣的阴茎长度=6.3英寸/16.0厘米，周长=4.8英寸/12.2厘米。这些使用三维模型对勃起阴茎大小偏好的初步估计表明，女性能够准确回忆尺寸，并且更喜欢仅略大于平均尺寸的阴茎。
