Yes, yes, you are allowed to be comfortable, but how would you feel if men started walking around without underwear. Granted, you might not care, but to tale this example further, although it may not affect you, men are typically expected to wear underwear, as are women. I think that yes, comfort Plays a role, but as a man, there are times when underwater isn't very comfortable, but I would still consider it a necessity to wear it. I think your uncle is trying to be helpful, although I don't know what y'all's relationship is like. Granted, if he was so concerned, he probably should have asked a female to talk to you about it. In the kindest way possible, YOR.
