To address the limited generalizability of previous research and advance our understanding of romantic love experiences mate preferences and physical attractiveness we conducted a large-scale cross-cultural survey study on these topics. A total of 404 researchers collected data in 45 languages from April to August 2021 involving 117293 participants from 175 countries. Aside from standard demographic questions the survey included valuable information on variables relevant to romantic relationships: intimate passionate and committed love within romantic relationships physical-attractiveness enhancing behaviors gender equality endorsement collectivistic attitudes personal history of pathogenic diseases relationship quality jealousy personal involvement in sexual and/or emotional infidelity relational mobility mate preferences and acceptance of sugar relationships. The resulting dataset provides a rich resource for investigating patterns within and associations across a broad range of variables relevant to romantic relationships with extensive opportunities to analyze individual experiences worldwide.Englishinfo:eu-repo/semantics/openAccessSEX-DIFFERENCES, EVOLUTION, JEALOUSY, MENArticle
