Yeah. The shame was the whole fucking point tho. Shame is the kink for many, just ask Grayson Perry.
Hypothesis only but....I'd wonder if linked to repressed/ abusive childhoods where adolescent sexualities develop intertwined with feelings of shame.
Have well meaning cries of "don't kink shame" just made it harder for people who get off on shame, leading the abusive ones to do stuff like this?
