It is very important to set an example. Yesterday in the showers after my swim there were two local guys in their 20s, both wearing back swim trunks and clearly good friends, chatting and washing for a little longer than necessary. I was fully naked throughout, making sure plump penis could be seen by them as I enjoyed the hot water. Although they showed no sign of getting naked, and were doing the towel dance later, I feel sure that if they come back alone rather than with their friend they will also understand that it is fine and fun to be fully nude and once they experience that they will never go back, and when they come again with each other they will be open about being men and having everything a man has.Good for you for providing a much needed example. Let's keep spreading the word by modeling behavior!
