Nude on public beach in Mexico

A few years ago my wife and I were at a nice resort in Mexico. It was somewhat remote with the next closest hotel about three quarters of a mile away. One afternoon she wanted to get a massage and nails done so I decided to go for a little walk along the water. The weather was awesome - not too hot and clear skies. The surf was low and water felt just right. As I reached the halfway point between the hotels, I realized I hadn't passed a single person in the 20 mins I had walked. Loving nudity as I do, I decided to walk to the edge of the dunes, strip, and tan for a little while on the towel I brought just in case the opportunity presented itself. After about 20 mins of complete enjoyment, I decided to take a quick walk down to the water. Maybe it was the risk of leaving the somewhat safety of my towel that really excited me. As I neared the water, I could see two women walking my way around the bend. They hadn't seen me so I scampered back to the towel. As I considered whether to put my trunks on or simply lay down, they rounded the bend. I quickly layed back and waited for them to pass. Within seconds I heard one of the ladies say, "OMG, that guy is naked." They giggled and continued on. After another 10 mins I was ready to head back to the hotel. As I walked down the beach I saw the women walking back in my direction. As we passed each other I wasn't sure whether to make eye contact, but as I did they both smiled without saying a word. How I wish I knew what they said as they saw the naked guy then later passed him on the walk back.
