Hi. I hope I'm not repeating something that you all already know... I found a brand of underwear that lets you choose the pouch size. They have sizez X, Y, and Z. X is normal size. Y is 50% larger than X. And Z is 50% larger than Y. So, that means that size Z's pouch is more than twice the size of normal underwear. Go to: http://www.skiviez.com/mensunderwear/skiviezunderwear.asp Then choose your style under the heading "Cotton Stretch Pouch Selection Men's Underwear". Within the style you prefer, you can then choose your pouch size. As a grower, I personally do not need this extra room, so I have not tried this underwear. I simply thought it might be useful for all you big guys. Enjoy!
