Kink shaming is learning what someone does in the privacy of their own home and shaming them for it.
Bringing their kink into the public space and forcing others to take part in it, like this, isn't kink shaming.
OP is forcing us into their kink without asking consent, and that should be shamed. OP should go to a kink community if they want to talk about this stuff.
I just wonder, what stories could there even be behind it? Incontinence isn't some kind of achievement you work hard for.
Unless we're talking about some nerve injuries from accidents.
