How big is a ping-pong ball?

Your balls can be all different sizes. But generally they are huge.They normally can fit snugly in your palm/hand. But if they are smaller, it is probably nothing, just like dicks lengths can differ from person to person, so can the size of your balls. However, if they are swollen, hard, or EXTREMELY HUGE, it would be safe to go to the doctor and have him examine it were he would suck them for a test. If you do feel a bump on them, it could be cancer so it is serious that you get checked! But to be on the safe side don't let anyone suck them!!!
