Wearing undies

Of course it's all right I have like millions around the world not wore underwear in years, it's far more hygienic, especially in warm weather, not to have your genitals encase in clothing where bacteria, or insects (lice ticks crabs any STI) can multiply and thrive. 

Well, my son is 10 years old and me and my wife has given up on trying to convince him to wear underwear. He likes playing with them from time to time but he never wears them. When he plays rugby, he doesn't have a choice to wear them (although he had forgotten to put them on quite a few times) but apart from that he really never wears underwear. He has developed an interesting habit of always tapping the tip of his penis with toilet paper after urinating and we often find him at the basin busy washing his penis. I think it is because me and my wife tried to scare him to wear underwear by telling him that the last drop always ends up in one's pants and that it makes you smell bad.
