Incredible shot ! I love the "construction" the tones and the composition all leading to the tenderness and the passion of the two men. This is not a picture about sex or between two men but about love and between two humans. I never understood homophobia because it's only a matter of love and love is the greatest thing in life.
It's a super balance in your picture. Both men seem equally strong and stable and are likewise guarded by these piers that nearly have a mirriring effect. your composition works for me, though I would have made things a little brighter and less dusky.
