This bonus content is a reading from Platypus, the CASTAC Blog. The full post by Rosario Rm can be read at https://blog.castac.org/2024/12/on-menstruation-and-feeling-shame/. About the post: Menstruation as a subject of study is not new. Margaret Mead, Mary Douglas, Chris Bobel, Miren Guillo, and Karina Felitti, among many others, have discussed how menstruation has been related to specific practices, and how taboos present great dynamism and variability as specific cultural constructions frequently linked to systems of bodily control and gender. In this article, I present the advances of research that explores how taboos associated with menstruation are reflected in the bodily and emotional trajectory of menstruating women and people through the implementation of a methodology based on the collective construction of emotional corpobiographies (Ramírez, 2024).
