Travelling widely has 'exposed' me to almost every variety of custom when it comes to nudity in changing facilities etc. Here are some instances.
1. I was a very shy, country boy when young, and did not expose myself at all when changing communally. A large towel deftly manipulated kept me suitably covered.
2. When family moved to the city, I noticed that city kids were generally uninhibited in my all-male school. Nude swimming was common, but despite the very liberal attitudes prevailing many of us preferred to keep covered. Our preferences NEVER received comment, either from staff or other pupils.
3. I noted that Catholic kids of my age who accompanied us swimming etc. never exposed themselves, presumably for moral/religious reasons.
4. When drafted into our military, I quickly realised that I had become a mere cog in an enormous machine and lost any inhibitions about nudity. We had very few private rights! After field manoeuvres, we considered ourselves lucky to be marched into one of the smallish communal outhouse shower facilities; our chief concern was to wash off the dirt, grime, oil, sweat etc. as soon as possible within the short time allowed. Recruits in training would frequently be supervised by a fully dressed orderly, to make sure we washed properly and quickly, so that no water-and-soap-shy guys were allowed to pollute the unit!
5. In more mature years I prefer open changing rooms, showers etc. with plenty of space. Some swimming-pools have 'modernised' their facilities by carving up open changing rooms into poky, cramped dressing cubicles, with almost nowhere to place clothes, shoes, other equipment etc. 'Unisex' showers are unsatisfactory since one can't remove swimwear and wash the parts that SHOULD be washed.
6. I have noticed a developing shyness among the young in recent years almost wherever I go. There are probably a plethora of reasons for this. Older men seem to be far less inhibited, and presumably are continuing to behave as they did back in their own youth.
