Hi Jeremy here, 28 yo Brit living in Amsterdam. Have never worn any underwear. My father is 53 he stopped wearing underwear at 14 and has never worn any since. So my folks never felt it necessary to make me wear any. Went direct from diapers from freeballing and have never had any underwear. Feels great. In usually wear either jeans or board shorts and the occasional business suit. Am also shirtless almost all the time even at work and quite often barefoot too. Kind of the son-of-hippies kind of guy and love every moment of it.
