Thanks for the response. I just wanted to comment on a few things.
Maybe, because you're gay, you will never know how wonderful it is to avert your gaze, knowing that doing so will help another man feel more comfortable with himself. I've had the experience of being in a gym shower and having good looking men enter the shower, and being curious about what this man has down below -- but rather than looking, I turned my back, knowing that doing so would make him more comfortable, and myself as well.
I don't mean to get all naively idealistic. But there is some level at which straight men do not objectify one another in the way that women do to one another and that gay men do to one another. It's very odd. On one hand, it would be nice to live in a society where everyone is so secure that when the well built young man enters the shower I could very easily look at his body without him being uncomfortable with that. But there's a level where the consideration of knowing that it would make him uncomfortable, and attempting to be considerate to him, is ultimately more important than actually seeing his body.
I'm probably going to anger some people with this statement, but I think that ultimately straight men bond in a deeper way than gay men. I recently read an article about sports psychology and behavior on the field. The writer, a woman, wrote, "Sacrificing your body for another male is the height of male bonding." I think that maybe straight men sacrifice themselves for one another in a way that gay men can't understand, such as the way I sacrificed my desire to look at the other male in the shower -- knowing that doing so would make him feel uncomfortable and objectified. At some level, NOT looking helped me experience his masculinity more than looking would have.
