This article explores the sexual subjectivity of women of post-reproductive age who seek partners on dating apps. The existing literature highlights the sexual subjectivity and agency of older women as contested and not sufficiently investigated. Even less research has been conducted on changes in the sexual subjectivity of women born in the USSR in the 1960s, with the liberalisation of sexual behaviour. The study is based on 45 interviews with women aged 55 years and over, who were born in the USSR and who now live in Israel, Finland and Russia. In the article, we examine sexual subjectivity as presented in the interviews from a life course perspective. We explain theoretically and empirically how changes in sexual subjectivity are expressed in the light of age and socio-cultural context constraints. Three life stories highlight the accumulation of experience and turning points, such as divorce and migration. They illustrate very different pathways in changing sexual subjectivity, yet all contain three Leitmotifs: desire, security and caring. The expression of post-reproductive female desire can be related to the need to feel secure and enjoy mutual care in sexual relationships. We show that these Leitmotifs shape and are shaped by women’s identifications as both sexual objects and subjects, and explore how they relate to different sexual cultures and variations in the socio-sexual positioning of women in Israel, Finland, and Russia.
