For me it’s because I have had to suffer from UTI’s before and I don’t want to risk some stream of water blowing bacteria into my vagina and then I gotta pee every five seconds and wait for a damn doctor visit because for some fucking reason UTI meds aren’t over the counter where I live.

I can buy the UTI “pain reliever” over the counter but it just temporarily fixes the pain, and the UTI of course continues. Pretty fucking pointless.
