A husky, awkward guy with a big Greek nose and patchy facial hair, my friend rubs the back of his head with a cringe. He has to be remembering an incident a few years ago, when we’d realized we were both into guys and immediately started comparing who we thought was hot, showing pictures to each other online—famous actors, nothing unusual.
