Introduction <p>In recent decades, risky online sexual behaviors in the digital environment have increased among adolescents. Although the literature has documented associations between these behaviours and various psychosocial variables, the simultaneous interaction from a gender perspective remains unexplored. This study analyses and compares these relationships in the adolescent population of the Basque Country (Spain).</p> Methods <p>A sample of 3,094 adolescents enrolled in educational centres in the Autonomous Community of the Basque Country (Spain). Differentiated psychometric networks were estimated for girls and boys, with each variable serving as a node, and edges representing regularised partial correlations. The differences between the two networks were compared using the Network Comparison Test.</p> Results <p>The structure of the networks differed significantly between boys and girls. In the girls’ network, risky online sexual behaviours showed greater interconnectivity, with online sexual victimisation being the most central node. Among boys, ambivalent sexism was more strongly associated with pornography consumption, whilst family support was associated with negative outcomes in relation to certain risk behaviours.</p> Conclusions <p>The findings suggest that risky sexual behaviours in digital environments during adolescence does not occur in isolation, but rather is shaped by an interrelated system of factors, the configuration of which differs according to gender. The study expands on previous research by offering an integrated view of these relationships.</p> Policy Implications <p>The results support the implementation of comprehensive, evidence-based, gender-sensitive programmes on affective and sexual education that address digital risks and reinforce the protective role of the family and social support during adolescence.</p>
