I went to Club Med in Hammamet when I was 20 with another blonde friend. When we walked away from the club beach to find quieter spots to sunbathe, we found an area by dunes that seemed more secluded. We didn't go nude as I'm sure that might be an offence, but we wore bikinis.
It wasn't long before we noticed a number of men watching us from the area of the dunes, trying to hide.
Eventually it became obvious that they had followed us and were masturbating whilst watching us sunbathe. Being young we weren't confident enough to tell them to leave us alone, and certainly not at a point in our lives where we would be curious to see more, so we packed up our stuff and got back to the Club Med pools where we felt safe.
I suppose this still goes on, so if your idea of a kinky day on the beach is to get naked, tease men hiding behind dunes and enjoy watching them masturbate and cum to you, then I would recommend you take a walk along the beaches there- just be sure you are safe !!
