Positive psychosexual development in adolescence is crucial to sexual health. Evidence suggests that adolescent’s psychosexual development is influenced by the sexual self-concept, relational skills, attitudes toward sexual pleasure, and sexual practices. To date, however, understanding of normative dispositions and experiences that positively shape adolescents’ psychosexual development remains limited. The goal of the study was to provide a descriptive analysis of adolescents’ perceptions of their sexual self, relational skills, and attitudes towards sexual pleasure as well as their sexual practices while considering age and gender differences. A Canadian sample of 1584 adolescents (49.7% girls, 49.4% boys and 0.9% gender diverse) aged 14 to 18 years old (M = 15.53, SD = 0.93) completed a self-reported questionnaire evaluating various aspects of sexuality and sexual practices. Results indicated that most youth are sexually active through autoerotic or partnered sexual practices, and that positive perceptions towards the sexual self, relational capacities and pleasure increase with age. Moreover, compared to girls, boys presented a more positive sexual self-concept, less positive perceptions of their relational skills and they were more likely to report autoerotic sexual practices. Cluster analysis supported classifying adolescents into the following profiles: positive, mildly positive, mildly negative and negative perception of the sexual self and sexuality. These profiles varied according to sexual practices, gender and age. This study provides further insight into general patterns and heterogeneity of adolescents’ sexuality that are relevant for adapting sexuality education and sexual health intervention.

青春期积极的性心理发展对性健康至关重要。有证据表明，青少年的性心理发展受性自我概念、关系技巧、对性快感的态度和性行为的影响。然而，迄今为止，对积极塑造青少年性心理发展的规范性倾向和经验的理解仍然有限。该研究的目的是在考虑年龄和性别差异的同时，对青少年对其性自我、关系技能和对性快感的态度以及性行为的看法进行描述性分析。加拿大 1584 名 14 至 18 岁青少年样本（49.7% 的女孩、49.4% 的男孩和 0.9% 的性别多样化）（M  = 15.53，SD = 0.93）完成了一份自我报告的问卷，评估性和性行为的各个方面。结果表明，大多数年轻人通过自体或伴侣性行为进行性活跃，并且对性自我、关系能力和快感的积极看法随着年龄的增长而增加。此外，与女孩相比，男孩表现出更积极的性自我概念，对他们的关系技能的看法不那么积极，他们更有可能报告自发的性行为。聚类分析支持将青少年分为以下几类：对性自我和性行为的积极、轻度积极、轻度消极和消极感知. 这些资料因性行为、性别和年龄而异。本研究进一步深入了解与适应性教育和性健康干预相关的青少年性行为的一般模式和异质性。
