I have always theorized that older men were so much more comfortable with nudity because they were all in the military at some point and are just used to it.  They also grew up in a time where it was not instantly assumed that two men naked in the same space must be gay for each other.  I'm 34, gay, and have spent plenty of time naked in locker rooms (steam rooms, saunas, hot tubs, etc) and analyzing what I felt to be bizarre behavior. I personally have no body shame and get naked as often as possible, but yeah, frequently the younger guys seem to be a little more inhibited than the older guys.
