Most of the overall population have the idea that they HAVE to wear underwear to be normal, but in reality underwear is only a recent invention, and because most people shower regularly there is no real need for it in these modern times.
Most men “go commando” from time to time; some men never wear underwear. It is mostly a matter of comfort and support.
I prefer freeballing because of the freedom associated with it.
