I notice on underwear websites they always have a curved nice package, but I always have quite a flat bulge?
It might be the type of underwear you are choosing? I find underwear that have a shaped pouch which support my balls and lifts them out from inbetween my legs and puts the whole package out front, the most visually pleasing. I have discovered
Lunch underwear which I find the best for visual impressiveness and support. I have more underwear than Imelda Marcos had shoes, but the only ones that I tend to wear nowadays are the Lunch underwear. Check my profile pics. You'll find that Lunch underwear manages to give me a nice curved package which matches the models on the website

Then again, maybe Lunch gives me a bigger package than the models on the website!

If you are unhappy with your bulge, try some bulge enhancing underwear like Lunch! Just a suggestion!
