Communal male nudity is HEALTHY, and a necessary part of maturation and growing up into adulthood.
Locker room nudity was common "back in the day" with P.E. classes in junior high and high school, and college. And talk about boot camp and the military... no privacy there. Everybody was an equal.
I was a little nervous when I was in seventh grade, but got over it quickly. You can too, and you SHOULD, for your own mental health. Time to man up.!
Today some of my best friends are my naked budds. We can hang out together in a yoga class, watching a movie, going camping and hiking, at the beach, diving, or just chilling. There is no sex, and no thought of sex. Well, maybe... but it never happens.
