【摘要】自慰行为（俗称：手淫）具有诸多健康益处，是大多数人性生活不可或缺的一部分，且通常贯穿于人生的各个阶段。然而，目前尚缺乏探讨自慰频率在人生主要阶段如何变化的纵向研究。本研究利用多层增长曲线模型，基于一个包含2562名个体的纵向人群样本，考察了19至50岁人群自慰频率的发展轨迹。对于女性而言，自慰频率呈逐渐上升趋势，直至30岁出头达到峰值，随后略有下降。相比之下，男性的自慰行为在所考察的年龄跨度内基本保持稳定。在控制了伴侣性行为频率这一变量后，两性的自慰轨迹均未发生改变。然而，若将伴侣关系状况及性幻想频率纳入考量，男性的自慰轨迹会发生变化，而女性的轨迹则不受影响。与已为人父母者相比，终身未育者在30岁左右之前表现出自慰频率更大幅度的增长，随后也呈现出更显著的下降趋势。在所有年龄段中，具有非异性恋性身份的参与者其自慰频率均高于严格意义上的异性恋者。此外，自慰轨迹在不同宗教信仰和受教育程度的人群之间未呈现出显著差异。综合来看，这些研究结果表明：作为一种性活动，自慰在频率上具有相对于伴侣性行为的独立自主性；同时也突显了个体的生活境遇及性特质在塑造其成年期自慰行为表现方面所发挥的重要作用。未来的研究应进一步深入探讨伴侣性行为、性功能及亲密关系问题，以及自慰行为之间相互作用的动态机制。
[Abstract] Masturbation with its numerous health benefits is an integral aspect of most people’s sexuality and is typically observed across all stages of life. However, longitudinal studies exploring the frequencies of masturbation across major life phases are lacking. We examined the development of masturbation frequencies from ages 19–50 via multilevel growth curve modeling with a longitudinal population-based sample of 2,562 individuals. For women, masturbation frequency gradually increased until they were in their early 30s, followed by a slight decline. In contrast, men’s masturbation practices remained largely stable across the investigated age span. Masturbation trajectories did not change for either gender when controlling for the frequency of partnered sex. However, accounting for partnership status and the frequency of sexual fantasizing changed the trajectories for men, but not for women. Compared to those who became parents, individuals who remained childless presented a greater increase in masturbation frequency until approximately age 30, followed by a greater subsequent decline. Participants with nonheterosexual sexual identity masturbated more frequently than did strictly heterosexual individuals, across all ages. Masturbation trajectories did not differ significantly across religious affiliation and educational attainment. Collectively, these findings suggest the autonomous nature of masturbation as a sexual activity in relation to the frequency of partnered sex but also underscore the importance of individual life circumstances and one’s sexuality in shaping its expression throughout adulthood. Future research should further investigate the dynamics among partnered sexual practices, sexual and relational problems, and masturbation.
