Masturbation is a common human behaviour. Compared to other unimanual behaviours it has unique properties, including increased sexual and emotional arousal, and privacy. Self-reported hand preference for masturbation was examined in 104 left-handed and 103 right-handed women, and 100 left-handed and 99 right-handed men. Handedness (modified Edinburgh Handedness Inventory, EHI), footedness, eyedness, and cheek kissing preferences were also measured. Seventy nine percent used their dominant hand (always/usually) for masturbation, but left-handers (71.5%) were less consistently lateralized to use their dominant hand than right-handers (86.5%). Hand preference for masturbation correlated more strongly with handedness (EHI), than with footedness, eyedness, or cheek preference. There was no difference in masturbation frequency between left- and right-handers, but men masturbated more frequently than women, and more women (75%) than men (33%) masturbated with sex aids. For kissing the preferred cheek of an emotionally close person from the viewer's perspective, left-handers showed a left-cheek preference, and right-handers a weaker right-cheek preference. The results suggest that hemispheric asymmetries in emotion do not influence hand preference for masturbation but may promote a leftward shift in cheek kissing. In all, masturbation is lateralized in a similar way to other manual motor behaviours in left-handed and right-handed men and women.
自慰是一种常见的人类行为。与其他单手行为相比，它具有独特的属性，包括增加性唤起和情感唤起，以及隐私性。本研究调查了 104 名左撇子女性和 103 名右撇子女性，以及 100 名左撇子男性和 99 名右撇子男性对手淫时惯用手的自我报告。还测量了手的偏向性（改良爱丁堡手偏向性量表，EHI）、足偏向性、眼偏向性和脸颊亲吻偏好。79%的人用惯用手（总是/通常）进行自慰，但左撇子（71.5%）的惯用手偏向性不如右撇子（86.5%）一致。自慰时的手偏向性与手偏向性（EHI）的相关性强于足偏向性、眼偏向性或脸颊偏好。左撇子和右撇子的自慰频率没有差异，但男性比女性更频繁自慰，而且更多的女性（75%）比男性（33%）使用性辅助器具自慰。从观察者的角度来看，亲吻亲密的人的喜欢的脸颊，左撇子表现出对左脸颊的偏好，而右撇子则表现出较弱的右脸颊偏好。研究结果表明，情绪的半球不对称性不会影响自慰时的手偏向性，但可能会促进脸颊亲吻时的左移。总之，自慰的偏向性与左撇子和右撇子男性和女性的其他手动运动行为相似。
