This study explores the European North-South differences in older partnered individuals’ silencing of the sexual self and its links to relational and individual well-being. A web survey was conducted among partnered individuals aged 65 years or above in Norway and Croatia. There were 368 (women: 37.8%, response rate: 22%) and 359 (women: 34.5%, response rate: 27%) individuals who participated in Norway and Croatia, respectively. A range of relational (sexual satisfaction, relationship quality) and individual well-being (anxiety, depression, and life satisfaction) indicators was considered. Sexual self-silencing had significant impacts across outcomes, gender, and countries. Furthermore, contrary to what might be expected, we observed no differences in self-silencing between the two countries; and in both countries, men were more self-silenced than women. Findings suggest that sexual self-silencing can compromise relationship quality and psychological well-being in later life. Health and clinical practice toward older individuals and couples should thus probe about and aim to improve the expression of sexual desires and needs.
