When I first saw this topic, I thought "Why would I want to hang with other naked guys?"
Then I remembered, I do it all the time. When at resorts, some of my pals and I would go off to help someone with a project like raising roof trusses for a new shed or add-on, hunt down a rattle snake or try the chili at the annual chili cookoff. I never thought of it as "hanging with the boys". But, I suppose that is what it was.
Opening a cold one after a hike or doing a job in the heat, sitting down and telling our stories about beautiful women, well, it seems natural enough to me!
I too like the enjoyment of other males together. I am in Edmonton, Alberta and winter is around the corner. During the winter blues we visit guy's places for the evening and hang out naked and have something to eat at the same time.
