Zach and Shawn...Shelter. The scene on the bed on the beach.
Bit of an obvious one but of course Heath and Jake in Brokeback.
The passionate kissing of Rupert Graves and James Wilby in "Maurice." Those two really gave it their all.
Honestly, any kiss between two men on film that is about love and NOT just sex brings tears to my eyes. For those of us old enough to have grown up with our true feelings always hidden and never demonstrated in mainstream media, it feels like dark heavy curtains being flung open and the sun streaming in. It feels like rebirth. It feels like we have the right to be here and experience what everyone else takes for granted.
