Muscular Man in White Swimsuit Flexing

This photo has an unusual feel, a spontaneous sort of natural "hey look at me" quality. The model in tight white trunks has a big smile and glint in his eye that suggests he likes being looked at. Is this a gay beach, maybe in Mexico? Sepia print on heavyweight matt Agfa paper, undated c. 1960s. No studio marks.8" x 10" in very good condition with minor bends and some discoloration at the bottom.
