There are many opinions on what shows your bulge the best. A few years ago I noticed guys at the gym wearing thin dazzle shorts or mesh shorts with boxers (or commando). You can often see the outline of the hanging penis in full detail, especially on the bench press. IMO, this look is sexier than an undefined mound in their shorts. Even if a guy is only 2" limp, seeing the ring around the penis head is a huge turn on for me. I was a briefs only guy until I made this observation. I started experimenting with boxers shortly thereafter, and found that I actually liked wearing them all the time. Not only will your maleness be more apparent in your clothes, but the looser fit is far more comfortable than being strapped up.
