There is a lack of recent data on the extent to which gay men engage in insertive anal intercourse (IAI) and receptive anal intercourse (RAI). Accurate assessments of the overall risk of infection from HIV and other sexually transmitted infections (STIs) require such data because versatile men who engage in both roles have heightened vulnerability for becoming infected and infecting others.
To investigate the extent to which gay men are versatile with regard to having IAI and RAI.
Percentages of gay men who reported engaging in IAI, RAI, or both during the past 12 months and in their most recent sexual encounter.
Eight hundred fifty-six Australian gay men completed an online survey to retrospectively report on their sexual practices over the past 12 months.
Of men who had anal intercourse in the past 12 months, 83% had both IAI and RAI, of whom 57% were highly versatile in that they had approximately equal numbers of partners for IAI and RAI. Of men who had anal intercourse in their most recent sexual encounter, as many as one in five (20%) had reciprocal anal intercourse, having both IAI and RAI with the same partner in a single encounter. Condom use was significantly less likely with reciprocal (38%) than nonreciprocal anal intercourse (50%; P = 0.04). While highly versatile men were less likely to know their HIV status, practices at most recent sexual encounter such as reciprocal anal intercourse and condom use were not significantly related to either their HIV status or that of their partner.
Engaging in both IAI and RAI appears to be common among gay men. HIV/STI prevention strategies would benefit from paying attention to the implications of high rates of versatile sexual practices, particularly the tendency for condoms to be used less often when having reciprocal anal intercourse.
目前缺乏关于男同性恋者进行插入性肛交（IAI）和接受性肛交（RAI）的程度的最新数据。准确评估艾滋病毒和其他性传播感染（STI）的总体感染风险需要这些数据，因为同时进行这两种角色的万能男性感染和感染他人的风险更高。
调查男同性恋者在进行 IAI 和 RAI 方面的万能程度。
报告在过去 12 个月内以及最近一次性行为中进行 IAI、RAI 或两者兼有的男同性恋者的百分比。
856 名澳大利亚男同性恋者完成了一项在线调查，回顾性地报告了他们在过去 12 个月内的性行为。
在过去 12 个月内进行过肛交的男性中，83%的人同时进行了 IAI 和 RAI，其中 57%的人非常万能，即他们的 IAI 和 RAI 伴侣数量大致相等。在最近一次性行为中进行过肛交的男性中，多达五分之一（20%）的人进行了互惠肛交，即在单次性行为中与同一伴侣同时进行 IAI 和 RAI。与非互惠肛交（50%；P=0.04）相比，互惠肛交时使用避孕套的可能性明显较低。虽然非常万能的男性不太可能知道自己的 HIV 状况，但最近一次性行为中的做法，如互惠肛交和使用避孕套，与他们自己或伴侣的 HIV 状况没有明显关系。
IAI 和 RAI 的同时进行在男同性恋者中似乎很常见。艾滋病毒/性传播感染预防策略将受益于关注高比例万能性行为的影响，特别是在进行互惠肛交时避孕套使用频率降低的趋势。
