This research longitudinally explored adolescent pornography (porn) consumption and its association with sexual development in early and middle adolescence. A four-wave design with half-year intervals investigated pornography consumption and different (sexual) activities, such as masturbation, French kissing, petting, giving/receiving manual and oral sex, and intercourse, among 630 respondents (47.9% female, mean age 13.7 years; SD = 0.48) years at T1). A latent growth mixture analysis of pornography consumption revealed two groups with relatively low pornography (LP; 51.8% of the boys, 91.4% of the girls) versus high pornography (HP; 48.2% of the boys; 8.6% of the girls) consumption across time. At T1, HP boys on average watched pornography less than once a month, but more than once a year at T1. At T4, their average pornography use had increased to almost one to two times a week. LP boys never watched pornography at T1. At T4, their average pornography use was still less than once a year. At T1, HP girls never watched pornography, but consumption increased to almost one to three times a month at T4. Across waves of the study, LP girls (almost) never watched pornography. A discrete-time survival mixture analysis of sexual developmental patterning indicated that, compared to their LP peers, both girls and boys in the HP groups showed accelerated development of masturbation, petting, and receiving manual sex. Girls in the HP group were also more inclined to receive oral sex, whereas boys in the HP group also showed earlier and more frequent manual sex and intercourse. Thus, whereas the HP group of boys was substantially larger compared to that of girls, pornography consumption was related to accelerated development of sexual activities for both genders across early and middle adolescence. The discussion deliberates on pornography as a driving force in adolescent sexual development versus pornography as a medium of choice for sexually advanced adolescents.
这项研究从纵向角度探讨了青少年色情制品（porn）消费与其在青少年早期和中期性发展的关联。本研究采用半年间隔的四波设计，调查了 630 名受访者（47.9%为女性，平均年龄 13.7 岁，标准差=0.48）在 T1 时的色情制品消费情况，以及不同的（性）活动，如自慰、法式接吻、爱抚、给予/接受手动和口交以及性交。对色情制品消费的潜在增长混合分析显示，有两个群体的色情制品消费相对较低（LP；51.8%的男孩，91.4%的女孩），而另两个群体的色情制品消费较高（HP；48.2%的男孩，8.6%的女孩）。在 T1 时，HP 男孩平均每月观看色情制品不到一次，但每年至少观看一次。在 T4 时，他们的平均色情制品使用量增加到几乎每周一到两次。在 T1 时，LP 男孩从未观看过色情制品。在 T4 时，他们的平均色情制品使用量仍不到每年一次。在 T1 时，HP 女孩从未观看过色情制品，但在 T4 时，她们的消费增加到几乎每月一到三次。在研究的各个波次中，LP 女孩（几乎）从未观看过色情制品。性发展模式的离散时间生存混合分析表明，与 LP 同龄人相比，HP 组的女孩和男孩在自慰、爱抚和接受手动性方面的发展都有所加快。HP 组的女孩也更倾向于接受口交，而 HP 组的男孩也表现出更早、更频繁的手动性和性交。因此，虽然 HP 组的男孩比女孩大得多，但在青少年早期和中期，色情制品消费与两性的性活动加速发展有关。讨论部分探讨了色情制品作为青少年性发展的驱动力与作为性成熟青少年选择媒介的双重作用。
