cool, just too much piss fetish
If you turn off urination emergencies and turn on the watersports content shield, it should prevent pretty much all the urination content as long as you don’t engage it yourself. There may be an occasional mention of pee from time to time as an ingredient, but it should be rare.
If you actively select watersports content by selecting an option to pee at some point, it should at least be blurred, other than a mention of ingredient collection. You can just not do that though, as long as urination emergencies are off, you won’t ever be forced to pee, just ignore the option.
