There are limited data on the patterns of early sexual behaviours among Australian teenage heterosexual boys. This study describes the nature and onset of early sexual experiences in this population through a cross-sectional survey.
A cross-sectional survey between 2014 and 2015 SETTING: Major sexual health clinics and community sources across Australia PARTICIPANTS: Heterosexual men aged 17-19 years RESULTS: There were 191 men in the study with a median age of 19.1 years. Median age at first oral sex was 16.4 years (IQR: 15.5-17.7) and 16.9 years (IQR: 16.0-18.0) for first vaginal sex. Most men had engaged in oral sex (89.5%) and vaginal sex (91.6%) in the previous 12 months with 32.6% reporting condom use at last vaginal sex. Of the total lifetime female partners for vaginal sex reported by men as a group (n=1187): 54.3% (n=645) were the same age as the man, 28.3% (n=336) were a year or more younger and 17.4% (n=206) were a year or more older. Prior anal sex with females was reported by 22% with 47% reporting condom use at last anal sex. Median age at first anal sex was 18.2 years (IQR: 17.3-18.8). Anal sex with a female was associated with having five or more lifetime female sexual partners for oral and vaginal sex.
These data provide insights into the trajectory of sexual behaviours experienced by teenage heterosexual boys following sexual debut, findings which can inform programme promoting sexual health among teenage boys.
关于澳大利亚青少年异性恋男孩早期性行为模式的数据有限。本研究通过横断面调查描述了该人群早期性经历的性质和开始情况。
2014年至2015年的横断面调查
澳大利亚各地的主要性健康诊所和社区来源
17 - 19岁的异性恋男性
研究中有191名男性，中位年龄为19.1岁。首次口交的中位年龄为16.4岁（四分位间距：15.5 - 17.7），首次阴道性交的中位年龄为16.9岁（四分位间距：16.0 - 18.0）。大多数男性在过去12个月内有过口交（89.5%）和阴道性交（91.6%），32.6%的人报告在最后一次阴道性交时使用了避孕套。在男性报告的一生中有阴道性交的女性伴侣总数（n = 1187）中：54.3%（n = 645）与男性年龄相同，28.3%（n = 336）比男性小一岁或以上，17.4%（n = 206）比男性大一岁或以上。22%的人报告曾与女性进行过肛交，47%的人报告在最后一次肛交时使用了避孕套。首次肛交的中位年龄为18.2岁（四分位间距：17.3 - 18.8）。与女性进行肛交与一生中有五个或更多口交和阴道性交的女性性伴侣有关。
这些数据为青少年异性恋男孩首次性行为后经历的性行为轨迹提供了见解，这些发现可为促进青少年男孩性健康的项目提供参考。
