Most of what the other guys have said is true. I can't wear a regular jock; they hang out the bottom of boxers; briefs are binding and painful; can't cross my legs; they create a huge mound in my clothes; guys stare at them in the locker room; getting racked seems to be a lot easier...and I wouldn't trade them in for anything! When I had a testicular cancer scare I was completely f'n freaked out! Luckily I didn't lose the ball. When I inquired the Dr. said the largest standard replacement size would be too small and wouldn't match...but that he could get one big enough that are made for dogs from the vet!!! Still haven't decided if I am flattered or insulted?!?!?!?! He didn't mention bull balls. :D :o ;)
