Sexual consent is one's voluntary, sober, and conscious willingness to engage in a particular sexual behavior with a particular person within a particular context. Sexual precedent theory posits that people believe that engaging in consensual sex at one point in time implies consent to later sexual encounters with that person. By assuming consent once a sexual precedent is set, people may rely less on communication cues. We sought to provide quantitative support for the claim that sexual precedent influences sexual consent in people's sexual relationships. To capture variability across sexual experiences, we collected daily sexual behavior data from each participant (n = 84) over a period of 30 days. We found a curvilinear relationship between sexual history with a partner and how people perceived consent during sexual activity with that partner (p = .003, ∆R = .089). A piecewise regression revealed that participants were less likely to report consent communication cues as sexual precedent increased until about 575 previous sexual behaviors (p = .003, R = .122); after this point, participants were more likely to report consent communication cues as sexual precedent increased (p = .028, R = .179). Overall, we provide the first quantitative evidence that consent conceptualization varies both within the person and across relationships regarding sexual precedent. In our discussion, we emphasize that sexual consent is contextual and cannot be assumed even after previous sexual encounters.
性同意是指一个人在特定情境下，自愿、清醒且有意识地愿意与特定的人进行特定的性行为。性先例理论认为，人们认为在某一时间点进行了同意的性行为，就意味着在之后与该人发生性行为时也同意。一旦设定了性先例，人们可能会更少地依赖于沟通线索来确认同意。我们旨在为性先例会影响人们性关系中的性同意这一说法提供定量支持。为了捕捉性行为经历的变异性，我们在 30 天的时间内从每个参与者（n=84）那里收集了每日性行为数据。我们发现，参与者与伴侣的性史与他们在与该伴侣进行性行为时对同意的感知之间存在曲线关系（p=.003，∆R=.089）。分段回归显示，随着性先例的增加，参与者报告同意沟通线索的可能性降低，直到大约 575 次之前的性行为（p=.003，R=.122）；在此之后，随着性先例的增加，参与者更有可能报告同意沟通线索（p=.028，R=.179）。总的来说，我们提供了第一个定量证据，表明同意的概念在个人内部和性关系中都因性先例而有所不同。在讨论中，我们强调性同意是情境性的，即使在之前的性行为之后也不能被假设。
