I agree that trunks with a little bit of spandex material in them are best. I found some at Target that I really liked - the 'seamless' kind with a lower rise band. The only drawbacks are that yes, you have to yank your pants and the trunks down to piss (no fly), and I have also found that I have to keep adjusting myself - by the end of the day sometimes, my balls are slipping out one leg because the legs are cut shorter than traditional boxer briefs. So, as much as I like them, there are downsides. It's hard to find a truly great pair of underwear!!! They DO look sexy - great on a butt and a nice package, and if you can get the low rise type...wow. I like the stretchy material and how nicely it fits your form too, without venturing into scary 'Speedo' territory (if you don't exactly have the body to pull off a Speedo, that is!). They're classy, almost.
As for Hanes boxer briefs - YUCK. I bought them once because I thought they would be great for all purpose wear, but there are awful. They sag and yes, there is almost too much material! Good question, Joe! Now get rid of those Hanes briefs and try and find something sexier that works! And make sure you respond back if you find anything so we all can go out and get 'em ourselves!
