Sexual risk behavior (SRB) includes behavioral (sex without contraception, sexualized substance use, sex work, sexual partner violence, other sexual activities that harm oneself or others) and affective subtypes (sexuality-related feelings of shame/guilt, relationship impairments) and leads to psychosocial and health-related consequences. Young adults comprise a vulnerable group regarding the development of SRB. The study aimed to identify SRB patterns among young adults and their relation to sexuality-related risk factors. A cross-sectional online survey measured behavioral and affective aspects of SRB with nine items. Latent class analysis was conducted to identify patterns of SRB. Gender, sexual orientation, age of first intercourse, number of sexual partners, hypersexuality, and sexual dysfunction were captured as risk factors via multinomial logistic regression. Within this convenience sample (n = 609; n_female = 365; n_male = 245; M_age = 23.1 years), the SRB patterns unremarkable (67%; low values in all SRB subtypes), shame-ridden (17%; high values in sexual feelings of shame/guilt) and risky sexual behavior (16%; high values in all subtypes of SRB, especially sexualized drug use) were identified. The shame-ridden and risky patterns were strongly associated with higher hypersexuality values, the risky pattern moreover with being non-heterosexual, of younger age at first sexual experience, and a higher number of sexual partners. Male and sexual minority participants demonstrated SRB more often than females and heterosexuals. Within prevention and treatment of SRB, it seems beneficial to address sexuality-related feelings of shame/guilt and addictive patterns (concerning sexual behaviors/substances) via gender- and diversity-sensitive measurements.

性危险行为（SRB）包括行为（不采取避孕措施的性行为、性物质使用、性工作、性伴侣暴力、其他伤害自己或他人的性活动）和情感亚型（与性相关的羞耻/内疚感、关系障碍）和导致心理社会和健康相关的后果。年轻人是SRB发展的弱势群体。该研究旨在确定年轻人中的 SRB 模式及其与性相关风险因素的关系。一项横断面在线调查通过九个项目测量了 SRB 的行为和情感方面。进行潜在类别分析以确定 SRB 模式。通过多项逻辑回归将性别、性取向、首次性交年龄、性伴侣数量、性欲亢进和性功能障碍视为危险因素。在这个方便样本中（n = 609；n_女性= 365；n_男性= 245；M_年龄= 23.1 岁），SRB 模式不显着（67%；所有 SRB 亚型中的值较低），感到羞耻（17%；高）确定了羞耻/内疚感的性感受值）和危险性行为（16%；所有 SRB 亚型的值都很高，尤其是性药物使用）。羞耻感和风险模式与较高的性欲亢进价值观密切相关，风险模式还与非异性恋、首次性经历的年龄较小以及性伴侣数量较多有关。男性和性少数参与者比女性和异性恋者更容易表现出 SRB。 在 SRB 的预防和治疗中，通过性别和多样性敏感的测量来解决与性有关的羞耻/内疚感和成瘾模式（涉及性行为/物质）似乎是有益的。
