This work builds upon recent work investigating erotic life and HCI, taking seriously the influences of interaction de-sign on our sexual wellbeing. In the present work, we critically analyze the ways that system design choices and emergent social behavior constitute an erotic social media platform and its concomitant expressions of desire. The site is called I Just Made Love, and it is used to share people's "love making" experience with others. We draw from continental cultural theory to analyze how the system and its users form arrangements of agency, which in turn lead to particular configurations of performed sexual desire. Based on our analysis, we argue that technosexuality is not just about using technology to fulfill an existing desire, but rather that novel forms of sexual desire come into practice because of particular constellations of design choices and social behaviors.
