Background

Comparing two convenience samples of college students in the northeastern region of the USA, this study sought to examine, by gender, whether there has been a change over the past two decades in the type and frequency of sexual behaviors heterosexual emerging adults report engaging in prior to their first coitus.

Methods

Sexual behaviors engaged in prior to coital initiation were extracted from our 2018 survey of college students (n = 293) and compared to published results from a similar survey conducted in 1995/1996 (n = 311). Mean comparisons and chi-square tests were used to evaluate gender differences among the 2018 cohort, and equality of proportion tests were used to compare the 2018 and 1995/1996 cohorts.

Results

Overall, a higher percentage of respondents in the 2018 cohort reported engaging in precoital activity as compared to the 1995/1996 cohort. Specifically, relative to the 1995/1996 cohort, masturbation significantly increased among both males and females; caressing partner’s genitals or giving oral sex significantly increased in frequency among females, and receiving oral sex significantly increased in frequency among males. A salient finding of this study is that the rate of increase in precoital sexual activity was greater among females than it was among males.

Conclusions

Health and education professionals seeking to facilitate the healthy sexual development of adolescents may want to consider broadening the scope of risk management strategies when working with heterosexual emerging adults, focusing not only on the coitally experienced population but also on adolescents who have not yet experienced coitus and may be engaging in other behaviors that pose a risk for STI transmission (e.g., oral sex).

初次交往之前青少年性行为的基于性别的世代比较

背景

通过比较美国东北地区两个大学生的便利样本，本研究试图通过性别调查过去二十年来，异性恋新兴成年人报告从事性行为的类型和频率是否发生了变化。到他们的第一个交往地点。

方法

从我们2018年对大学生的调查中（n  = 293）提取了性交开始之前发生的性行为，并将其与1995/1996年进行的类似调查（n  = 311）中公布的结果进行了比较。均数比较和卡方检验用于评估2018年队列之间的性别差异，均等检验用于比较2018年和1995/1996年队列。

结果

总体而言，与1995/1996年队列相比，2018年队列中受访者报告从事性行为前活动的比例更高。具体而言，相对于1995/1996年队列，男性和女性的手淫都明显增加；爱抚伴侣的生殖器或进行口交的频率在女性中显着增加，而接受口交的频率在男性中显着增加。这项研究的一个显着发现是，女性的性交前性活动增加率高于男性。

结论

寻求促进青少年健康性发育的健康和教育专业人员，在与异性恋新兴成年人合作时，可能不妨考虑扩大风险管理策略的范围，不仅要关注有性经验的人群，而且还要关注尚未经历过性交和性行为的青少年。可能正在从事其他可能导致性传播感染传播的行为（例如口交）。
