Sexual relationships in young adulthood may have important ramifications for individuals' physical and emotional well-being. Nonetheless, representative information about young adults' sexual activities in long-term relationships and the emotional context of such relationships is rare.
A subsample of 6,421 participants in Wave 3 of the National Longitudinal Study of Adolescent Health (18-26-year-olds) who were in a sexual relationship of at least three months' duration were selected for analysis. Multiple logistic regression models were used to explore the relationship between love and various sexual activities.
Eighty percent of respondents had engaged in cunnilingus and fellatio as well as vaginal intercourse in their current relationship; this group included 22% who also had engaged in anal sex. Compared with their peers who reported that they and their partner did not love each other a lot, both males and females who reported mutually loving relationships had significantly higher odds of having given oral sex (odds ratios, 3.9 and 2.6, respectively) and having received oral sex (1.8 and 3.3); males in mutually loving relationships also had elevated odds of having had anal sex (3.1).
Most young adult couples in long-term relationships engage in a variety of sexual practices with loving partners; the direction of causality in this association and its implications for relationship building require exploration. Furthermore, programs and interventions that address health and well-being during emerging adulthood should cover issues relevant to a broad range of sexual activities, including oral and anal sex.
青年期的性关系可能对个体的身心健康产生重要影响。然而，关于青年在长期恋爱关系中的性活动以及此类关系中的情感背景的代表性信息却很少见。
从全国青少年健康纵向研究第三波的6421名参与者（年龄在18 - 26岁）中选取了一个子样本进行分析，这些参与者处于至少持续三个月的恋爱关系中。使用多元逻辑回归模型来探究爱情与各种性活动之间的关系。
80%的受访者在当前恋爱关系中进行过口交、舔阴以及阴道性交；这一组中22%的人还进行过肛交。与那些表示自己和伴侣不太相爱的同龄人相比，报告相互爱慕关系的男性和女性进行口交（优势比分别为3.9和2.6）以及接受口交（1.8和3.3）的几率显著更高；处于相互爱慕关系中的男性进行肛交的几率也有所增加（3.1）。
大多数处于长期恋爱关系中的青年情侣会与相爱的伴侣进行各种性行为；这种关联中的因果关系方向及其对关系建立的影响需要进一步探究。此外，针对成年早期健康与幸福的项目和干预措施应涵盖与广泛的性活动相关的问题，包括口交和肛交。
