I don't like swimming pools.

Grew up swimming in lakes and the ocean, and prefer to swim in open water. Wouldn't know how to behave with lane markers.

I didn't do the poll cuz "never" doesn't fit me. I'd say "not generally". There are times I get scared, like when a boat is coming in my direction (probably an irrational fear cuz there are swimming area markers the boats stay away from). And I do get the creepy crawlies when a dead fish floats by or a hunk of lakeweed bumps my skin.

I'm more afraid of the other swimmers in a tri than of the water/lake/bay itself.
