"I Don't Want To Hear About Your Dick": Communicatively Managing Stigma Surrounding Foreskin Restoration, Joshua Hartelt
"I Don't Want To Hear About Your Dick": Communicatively Managing Stigma Surrounding Foreskin Restoration, Joshua Hartelt
Electronic Theses and Dissertations
Goffman (1963) defined stigma as an individual being unable to receive social acceptance because of a specific characteristic by being marked based on a characteristic, which can visible or invisible. This study examined how men undergoing foreskin restoration communicatively manage the stigma associated with restoring their foreskin. Through 13 interviews, I was able to thematically code using Meisenbach’s (2010) stigma management communication typology which served as an excellent theoretical fit. My results suggest that men undergoing foreskin restoration deploy several sub-strategies to manage stigma, as well as utilize multiple strategies simultaneously. Furthermore, my results indicate the possibility of new stigma …
