This is the problem with big government and searches. We have a right to privacy, I believe. I simply don't agree with "If you've got nothing to hide, you've got nothing to worry about." There are things (usually sexual) that really are no one's business.
On the other hand, in this day and age, it's not wise to travel with a penis pump.
If the guard is right, that means he'd rather his mother thought he was carrying a bomb than a penis pump. His mother already knows he has a small penis, no?
what can I say bro, you'll just have to do some serious pumping right before the trip and hope it lasts until you get to the destination where you could probably buy a local pump
