Hah, I was skinnydipping with some friends. At one point I got out of the water and sort of kneeled/squatted by a rock. I was trying to stay low because I didn't want to draw attention to myself. One of my friends was in the water behind me and he started laughing and joking that he could see my cock hanging below my ass and it looked like a racehorse peeing! I laughed too, but his joke kind stayed with me and turned me on later when I thought about it. (I must have looked something like this nude picture from my gallery.)
