Sexual debut experience may influence HIV/sexual risks among men who have sex with men (MSM). We assessed associations between age of sexual debut and sex of debut partner with recent (past-3-month) sexual/HIV/syphilis risks among 3588 community-based Chinese MSM. Sexual debut with women was associated with more recent (condomless) insertive anal sex with men, more recent (condomless) vaginal sex, and more lifetime female partners. Sexual debut with men was associated with more recent (condomless) receptive anal sex with men and more lifetime male partners. All associations were strongest among those having first sex ≤18 years in both groups. Earlier sexual debut was associated with higher HIV/syphilis risk; HIV risk was higher with first sex with a man, but syphilis was higher with first sex with a woman. Earlier age of sexual debut is associated with greater HIV/syphilis and sexual risks, but MSM risk differs with first sex with women versus men.
首次性行为经历可能会影响男男性行为者（MSM）的艾滋病毒感染/性风险。我们评估了3588名社区招募的中国男男性行为者首次性行为的年龄和首次性伴侣的性别与近期（过去3个月）性传播感染/艾滋病毒/梅毒风险之间的关联。与女性的首次性行为与近期（无保护）男性插入式肛交、近期（无保护）阴道性交以及更多的终身女性性伴侣有关。与男性的首次性行为与近期（无保护）男性接受式肛交以及更多的终身男性性伴侣有关。在两组中，首次性行为年龄≤18岁的人群中，所有关联最为强烈。较早的首次性行为与更高的艾滋病毒/梅毒风险相关；与男性首次性行为的艾滋病毒风险更高，但与女性首次性行为的梅毒风险更高。较早的首次性行为年龄与更大的艾滋病毒/梅毒及性风险相关，但男男性行为者与女性或男性的首次性行为风险有所不同。
