Currently, social networks are places where young people socialize and develop their digital identities. One of the most common risky behaviors among young people is sexualized behavior, which is promoted in social networks due to an interface that makes content exchange easier, for example, by sharing pictures, messages, videos, etc. This study's aim is to analyze the sexualized behaviors displayed by adolescents and young people on their Facebook profiles and the factors that allow for their distribution over social networks. In order to achieve this objective, a content analysis was performed over the course of 12 months using 100 profiles of teenagers and adolescents in Spain between 14 and 21 years of age. The results revealed differences in gender for these types of behaviors, and vulnerability factors were found to be part of this problem. The self presentation in the digital egocentrism and digital narcissism strengthen sexualized behaviors. Selfies represent a particular way of communicating with others and are responsible for most of the sexualized behaviors.Finally, avoiding the creation and/or diffusion of sexualized behaviors is highly important, and there is an urgent need to educate young people so they can learn how to manage their virtual media. Internet and Social networks bring the opportunity to research the adolescence and youth's world.Privacy settings are a facilitating factor for sexualized behaviors.Girls tried to please through seduction to obtain social approval while boys presented themselves as seducers.
