You Sim will also be reluctant to take showers/baths and will cry after doing so. There is no consequence for doing so, however and it can be pretty entertaining to watch, if nothing else.

I had a family where the father had this trait. I thought it was harmless, but then they all went to a pool party. And somehow, even though he supposedly hates the water, he ended up in the water and then drowned because he seemed to refuse to swim. I was too busy playing the mother to notice until it was too late and the Grim reaper was coming. The downside to hydrophobia.
