For a meditation on water, and then water and sex, here is an entrancing soundtrack by the Robert Horner Percussion Ensemble (steel drum band), entitled Songlines, for a Caribbean ambiance:
and here is a visual,
Some serene weightlessness,
And a jellyfish fantasy,
Now some human floating,
and next some floating and sex,

A couple more of our dolphin buddies,
But wait, here is a last one with some of the swimmers meditating on water and at least food, maybe sex too, who knows?
