Estimates show a 50% lifetime human immunodeficiency virus (HIV) risk among Black men who have sex with men (BMSM) in the United States(U.S.). Studying the dynamics of sexual positioning practices among BMSM could provide insights into the disparities observed among U.S. groups of men who have sex with men (MSM). This study explored sexual positioning dynamics among HIV-negative BMSM and how they aligned with a theoretical model of sexual positioning and HIV/sexually transmitted infection (STI) risk among MSM. In-depth qualitative interviews were conducted with 29 HIV-negative BMSM between ages 25 and 35 in Los Angeles. Comments related to sexual behaviors were reviewed for relevance regarding oral or anal sexual positioning practices. Data presented represent the range of themes related to decision making regarding sexual positioning. Personal preference, partner attraction, HIV avoidance, and feeling obligated to practice partner preferences influenced sexual positioning. Drug use also affected decision making and was sometimes preferred in order to practice receptive anal intercourse. These variables build on the conceptual model of sexual positioning practices and sexual risk, and add understanding to the relationship between preferences, practices, and risk management. Future research on risk among HIV-negative BMSM should quantify the relative impact of personal preferences, partner attraction, partner type, compromise, and substance use on sexual positioning practices and risk.
研究表明,在美国,与男性发生性关系的黑人男同性恋者(BMSM)一生中感染人类免疫缺陷病毒(HIV)的风险为 50%。研究 BMSM 之间的性体位实践动态可以深入了解美国男同性恋群体之间存在的差异。本研究探讨了 HIV 阴性 BMSM 之间的性体位动态,以及它们如何与男男性接触者(MSM)中的性体位和 HIV/性传播感染(STI)风险的理论模型相一致。在洛杉矶,对 25 至 35 岁之间的 29 名 HIV 阴性 BMSM 进行了深入的定性访谈。对与性行为相关的评论进行了审查,以确定其与口交或肛交体位实践的相关性。呈现的数据代表了与性体位决策相关的主题范围。个人偏好、伴侣吸引力、HIV 回避以及有义务实践伴侣偏好影响了性体位。药物使用也会影响决策,有时为了进行接受性肛交而更喜欢使用药物。这些变量建立在性体位实践和性风险的概念模型之上,并增加了对偏好、实践和风险管理之间关系的理解。未来针对 HIV 阴性 BMSM 的风险研究应量化个人偏好、伴侣吸引力、伴侣类型、妥协和物质使用对性体位实践和风险的相对影响。
