Using data from an undergraduate probability sample, we aimed to: (1) describe the prevalence and demographic characteristics of students who reported having engaged in rough sex with their current partner; (2) assess which sexual behaviors students consider to be rough sex; (3) describe the frequency with which participants report engaging in rough sex as well as their reports of initiating and liking rough sex, in relation to gender and sexual identity; and (4) examine predictors of rough sex frequency. Participants were 4998 students randomly sampled from a large Midwestern university who completed a confidential Internet-based survey (2453 women, 2445 men, 41 gender non-binary, 36 transgender or other gender non-conforming identities). Within these, 1795 individuals who reported a romantic/sexual partner of at least 3 months responded to questions about engaging, liking, and initiating rough sex. The most common behaviors participants considered to be rough sex were choking, hair pulling, and spanking. Transgender and gender non-binary students more often endorsed behaviors as rough sex. Also, rough sex was conceptualized as multidimensional, with one cluster being more consistent with earlier conceptualizations of rough sex (e.g., hair pulling, spanking) and the second cluster including behaviors such as choking, slapping, punching, and making someone have sex. About 80% of those with a current sexual or romantic partner engaged in rough sex with them and most who engaged it liked it. Bisexual women reported greater rough sex frequency and enjoyment (54.1% indicated enjoying it “very much”). Implications for sexuality research and education are discussed.

使用来自本科概率样本的数据，我们旨在：（1）描述报告与当前伴侣发生粗暴性行为的学生的普遍性和人口统计学特征；(2) 评估学生认为哪些性行为是粗暴的性行为；(3) 描述参与者报告从事粗暴性行为的频率以及他们开始和喜欢粗暴性行为的频率，与性别和性身份有关；(4) 检查粗暴性频率的预测因子。参与者是从一所大型中西部大学随机抽样的 4998 名学生，他们完成了一项基于互联网的保密调查（2453 名女性、2445 名男性、41 名非二元性别、36 名跨性别或其他性别不符合身份的人）。其中，1795 名报告有至少 3 个月浪漫/性伴侣的人回答了有关参与、喜欢和发起粗暴性行为的问题。被认为是粗暴性行为的最常见行为是窒息、扯头发和打屁股。跨性别和性别非二元学生更经常将行为视为粗暴的性行为。此外，粗暴性行为被概念化为多维的，其中一个集群与早期粗暴性行为的概念化（例如，拉头发、打屁股）更一致，第二个集群包括窒息、拍打、拳打和让某人发生性行为等行为。大约 80% 的现有性伴侣或浪漫伴侣与他们进行粗暴的性行为，并且大多数参与其中的人都喜欢这种行为。双性恋女性报告的粗暴性行为频率和享受程度更高（54.1% 表示“非常”享受）。
