Hey Govteenguy:
I looked at your gallery, and you have all the right stuff - a great body and cock. You're good to go there.
As Ineligible stated, briefs can make a nice bulge, but often the details are obscured. Boxer briefs will often hide the details, too. If a guy's pants aren't too loose, and he freeballs or wears boxers, it's easy to see the outline of the guy's dick because it hangs loosely instead of being supported and held close to the trunk of the body. Mesh gym short, track pants, sweat pants, and lighweight khaki pants, especially light colors, are great for showing cock when you wear boxers. Experiment with your clothes and underwear and I bet you'll find what you're looking for.
