Boxer briefs. I'd like the elastic around my legs, I think, because briefs leg holes look like they'd rub on the underside of where your butt and legs meet. Some of our underwear does that, and it's kinda uncomfortable. I like wearing a bra, for support, though ... so I wouldn't want my balls bouncing around in boxers, either.
I don't get the 'Boxer' thing, as your stuff is just dangling, and when you sweat, things get sticky, and that isn't comfortable. I don't like my stuff sticking to my leg, or maybe going its own way!! It has enough 'say' with erections, so why give it more freedom? I prefer I nice Calvin-type guy-bikini, that shows it off, but supports. Balls are a lot like breasts, and are subject to GRAVITY! I don't want my balls at my knees when I retire!! Besides, there are a lot of things between 'tighty whities' and 'boxers'!! Go to undergear. com and just enjoy!!
