A catcall is entirely about reminding you that you are not yours. The purity myth is entirely about reminding you that you are not yours. The fetishization of female purity in a world where catcalls are an acceptable form of communication telegraphs one thing very clearly:
“Women, stop sexualizing yourselves—that’s our job, and you’re taking all the fun out of it.”
The sexualization of women is only appealing if it’s nonconsensual. Otherwise it’s “sluttiness,” and sluttiness is agency and agency is threatening.
