This has such a relaxed feel to it I think it is lovely The only thing that jarred a little with me was the word wandering in this line

wandering
aimlessly on my back
I associate wandering with walking and wonder if drifting or floating might not perhaps be a better choice as you are talking about floating in water. A little more punctuation is required IMO but regardless of these nit picks it is a lovely poem
