In her empirical study, Janina Fandel provides a deep insight into the dynamics of friendships with the sexually preferred sex. She highlights the challenges and potential benefits of these relationships from an evolutionary psychological perspective. While most research to date has focused on heteronormative relationships, this study is one of the first to include homosexual individuals. By demonstrating that there are differences between the sexes and also regarding the sexual orientations, the author makes a significant contribution to the understanding of human relationships and to further scientific discourse.
