I don't do much actual swimming, but a lot of bathing / jumping around in the water / splashing etc...
I still remember taking swimming lessons when I was 5 or 6. One of the instructors (unbelievably) thought I already knew how to swim and he threw me in the deep end. They had to come and pull me out. It wasn't a fun experience but luckily it didn't keep me away from pools for the rest of my life.
