Lesbians have long turned to digital media and technologies for information, support, and to self-represent sexual identity in ways that have the capacity for building communities and gathering publics and counterpublics. TikTok is a short video platform popular with young people, which has increasingly seen the participation of comparatively older users. This paper investigates the self-representation of lesbians over age 30 on TikTok to understand the themes in their content and how the platform shapes their communication with others. Through sampling tailored to TikTok's algorithmic curation, ten lesbians' accounts are examined alongside qualitative coding and analysis of 50 of these creators' videos. Findings reveal key themes regarding the expression of identity and age, lived experience over time, and bids for connection and community. TikTokers expressed lesbian identity in continuity with longstanding stereotypes to enhance visibility but also incorporated humor and youthful trends to give rise to novel identity expressions. Videos showcasing the passage of time and sociopolitical change demonstrated the resilience of lesbian lives and conveyed hope while advice and statements of solidarity expressed support for young people's present struggles with homophobia and transphobia. Contrasting with studies of TikTok's generational wars, this article shows how older lesbians are building generational bridges through their uptake of youth-driven platform practices, sharing of past challenges to support youth in overcoming present hurdles, and by modeling lesbian futures.
