Meh. I went without underwear for a while. It’s kind of freeing when I’m at home, but those times I have to run out and forget to put on shorts or pants without a belt, it’s a little stressful lol. The first thing my wife does when she gets home is takes her bra off, so I ultimately guess it could be the same, but there’s no social impacts if men don’t wear underwear under their trousers when in public
