[NSFW possibly] What is/are your favorite water sports?

Here it is the dog days of summer. With the massive bubble of high pressure that’s sealed America’s heartland in a pressure cooker for the past several weeks, and temperatures soaring all over the northern hemisphere; this has to be the time to get to the lake, river, pond, beach or pool. To those jellies in the southern hemisphere, perhaps you’re far enough into winter to miss the heat and you’re now dreaming of sailing, surfing or what have you.

Of course, just in case you turn to an air-conditioned playroom for your particular water sports, I included the possibility for NSFW answers.

What wets your whistle when things get too darned hot?
