Contributing to the field of the geographies of digital sexualities, this article explores the geosocial dimensions of digital sexual cultures by analyzing three regionally operating, linguistically specific social media platforms devoted to sexual expression. Drawing on case studies of an Estonian platform used primarily for group sex, a Swedish platform for kink and BDSM, and a Finnish platform for nude self-expression, we ask how these contribute to and shape sexual geographies in digital and physical registers. First, we focus on the platforms as tools for digital wayfinding and hooking up. Second, we consider how the platforms help to reimagine and sexualize physical locations as ones of play, and how this transforms the ways of inhabiting such spaces. Third, we analyze how the platforms operate as sexual places in their own right, designed to accommodate certain forms of display, relating, and belonging. We argue, in particular, that these platforms shape how users imagine and engage with location by negotiating notions of proximity and distance, risk and safety, making space for sexual sociability. We approach geographies of sexuality both through the regional and linguistic boundaries within which these platforms operate, as well as through our participants' sense of comfort and investment in local spaces of sexual play. As sexual content is increasingly pushed out of large, U.S.-owned social media platforms, we argue that locally operating platforms provide a critical counterpoint, allowing for a vital re-platforming of sex on a regional level.
