Maybe I just haven't shopped around enough. All the major dept stores I've been to, there's nothing in terms of selection that is comparable to the lycra/nylon/spandex combo that women's underwear is made out of. Men's underwear is usually always made of cotton & polyester. When you compare the two side by side, the men's underwear is so harsh - it doesn't make sense why you would even wear it. Hey, I own a pair of silk boxers, but boxers, in general, serve no purpose IMO - since you're really just wearing shorts...underneath your shorts. I guess the only purpose they might serve, is to provide a 'comfort' layer between you and your trousers, shorts, jeans, etc. But me personally, I don't own/wear any pants or shorts that are THAT uncomfortable (they've come a long way with making denim & khakis very comfortable).
But yeah, if I could find a pack of men's briefs, that were made out of the same stuff your typical women's underwear is - I'd be all over it. But as it is, all I've seen is heat-retaining (unhealthy), rough, heavy materialed, constricting, improperly cut (bad fitting), anyting BUT soft and smooth, uncomfortable things to choose from.
But yeah, maybe I just haven't shopped around enough. I've gone completely without underwear (for my usual/typical, everyday life) for a number of years (3 or 4 maybe) now, so I've gotten pretty used to it. The main reason I stopped, was because I lived (and continue to live) in a hot & humid part of the country, and I just got tired of killing all my sperm.

Plus, when that area of the body is hot - it just raises the whole body temperature... and I HATE being hot.
I used to just (significantly) stretch my briefs in the front - with my fist, so that they would be nice and loose. But after a while, I thought, 'hey - what's the point of this, anyway?'
I think this is the way to go, actually. But, there is winter time... and it would be nice if they made some men's underwear out of the same stuff they do women's.
