I've tried a lot of different types of underwear. I've got to say, there's nothing better for supporting your cock and balls and showing off your balls than a thong, but there not easy to get used to. Pouch underwear are great for showing it, too. Boxer briefs and trunks create a nice outline for your package, especially when their white. I do prefer boxers though. There freeing and let your cock and balls move freely and naturally. There breezy and as close as you can get to going commando in underwear. Depending on the style, they don't always show much, but I've got enough junk that boxers can't hide it.
