Not sure this qualifies, but years ago in the Navy, I was at a bar in Norfolk and met this absolutely gorgeous hunk. He was a little shorter than me, had blond or light brown crewcut hair, a great tan complexion, shown off quite well in his muscle shirt. And he had the muscles to make it work - arms, shoulders, and chest. And a really "butch" outgoing manner to him. I loved this kid!
But I wasn't the only one. Another guy was buzzing around him, also making goo-goo eyes at my intended, who was unfortunately getting drunker as the night progressed. Forgetting some details, the three of us wound up in the dunes of Sandbridge Beach and made out, each of us taking turns with the hunk. At some point, the hunk and my competition went further into the dunes while timid me sat alone in the moonlight, wishing and wondering. When they came back, both seemingly satisfied, we returned to Norfolk and went our separate ways. I returned to that bar several times hoping to find the hunk again, but never did. Clearly-and sadly- a missed opportunity, and although gone for many years, never forgotten.
