I'm a big fan of briefs with a pouch in front. While I'm definitely a "shower" -- usually about 6.5" soft, and thick -- it's the size of my balls that really makes a pouch essential. (Mine are about 2.5" diameter apiece; my wife compares them to plums.) I'm also quite muscular (5'7 and 195 lbs.), so without some sturdy separation of things down there, I end up with way too much sweaty/itchy scrotum-thighs contact.
Obviously was the first brand I tried, and I continue to love some of my older pairs. They are extraordinarily comfortable for a guy built like me, with a very generous pouch and extremely stretchy yet supportive fabric. I moved away from them because delivery from the company, in Australia, was slow/expensive (they are probably now available from many places other than obviously.com.au, but this was not the case circa 2010). More importantly, the company evolved away from largely hung-friendly products into underwear geared toward more average guys, and I find to difficult to ascertain on their website which styles are the older, hung-appropriate ones. I don't want to spend $25 for a pair of briefs, plus shipping, only to realize that it's a similar but more mainstream style.
After Obviously, I moved to briefs from
John Sievers, which is a house brand of internationaljock.com -- only available there, as far as I know. These are very similar to the Obviouslys (see my avatar, and many of my album pics), with a huge pouch and very stretchy/supportive fabric. The colors are, I think, a bit better than what Obviously offers (if you care about that); shipping is much quicker and cheaper; and the briefs regularly go on sale. I have always been extremely happy with John Sievers, and they're now my go-to brand.
(One note for hung guys who are considering buying these: The cotton John Sievers, which generally have contrasting stitching or piping, are much tighter than the others, since cotton stretches quite a bit less than the bamboo/lycra blend found in most of their underwear. They are good to wear if you want a bit more confinement/support, such as for running or to wear under tighter dress pants, but I find these a lot less comfortable. All of my pics here are the bamboo/lycra John Sievers, NOT the cotton.)
(One other note: Both Obviously and John Sievers also offer boxer briefs. I personally prefer the briefs, for two reasons: 1. Since I'm muscular, the legs of boxer briefs tend to be tight on me. And while I've sometimes had trouble with glutes coverage in other briefs, Obviously and John Sievers briefs are cut generously enough in back even for very meaty cheeks. 2) The briefs allow a much more natural hang -- see my pics -- which I find a lot more comfortable. Any pouched boxer brief, in my experience, tends to hoist everything front-and-center, which I find both less comfortable and way more obvious under jeans or dress pants -- not what I am going for. It usually shocks people to hear that as showy as these briefs are when worn alone, the bulging is actually pretty inconspicuous under pants.)
I only recently tried Andrew Christian's "Trophy Boy" briefs. I have to say that despite all the talk about them here -- and their over-the-top "for guys who are HUNG" marketing -- I've been wildly underwhelmed. The pouch, I think, is much smaller than either Obviously or John Sievers, and the fabric is way tighter. I find my Trophy Boys to be uncomfortably confining, to be honest, and almost never wear them. I guess maybe they'd be better suited for guys who are more like 4-5" soft, and/or who have more average balls.
And, as the OP noted, the styling's not for everyone -- pretty flamboyant. I'm OK with pink or purple from John Sievers, so I'm no prude, but the waistbands of a lot of the Trophy Boys are practically rainbow flags -- and the screaming TROPHY BOY text is embarrassing if you're like me, and exercise near where you work. No way would I let professional colleagues see me in these!
Hope this is helpful to anyone who's faced similar underwear issues. Happy to chat via private message or whatever with anyone who has further questions.
