Have you ever seen a man with an erection at a nude beach? What happened?

I used to go to nude beaches all the time. I would usually tan then lay on my back and fall asleep for 30-60 minutes. I would "always" wake with an erection. Straight up in the air. People all around me and some looking at me. I would simply get up, walk to the water and cool off or lie and wait for my hard on to go down. Not a big deal.
