The present study tests the assumption that peers wield sufficient influence to induce sexual homophily (i.e., similarities in sexual experiences). Because girls face greater stigma for their sexual experiences than do boys, sexual homophily may be greater in girls' friendship networks than in boys'. Stochastic actor-based models were used to analyze network data (n = 2,566; ages 14-18) from two high schools in the National Longitudinal Study of Adolescent to Adult Health. Sexual homophily was present in friendship networks. Girls and boys were equally susceptible to their friends' influence, but the former exhibited a stronger preference for befriending same sexual debut status peers than the latter. The findings suggest that adolescents-particularly girls-"curate" their networks to minimize peer ostracism.
本研究检验了这样一个假设，即同龄人具有足够的影响力来促使性同质性（即性经历的相似性）。由于女孩的性经历比男孩面临更大的耻辱，因此女孩的友谊网络中的性同质性可能比男孩的更大。基于随机主体的模型被用来分析来自国家青少年到成人健康纵向研究中的两所高中的网络数据（n=2566；年龄 14-18 岁）。在友谊网络中存在性同质性。女孩和男孩同样容易受到朋友的影响，但前者比后者更倾向于与同性初次性经历的同龄人成为朋友。研究结果表明，青少年——尤其是女孩——“策划”他们的网络，以最大限度地减少同伴排斥。
