I have a friend who is a TSA. They have seen much worse, it probably won’t phase them. A penis pump obviously can’t blow up a plane, so they have no grounds to give you a hard time for it. Random things she has found in checked luggage:
- Live fish. Not in water or anything, just laying on someone’s dirty skivvies gasping for oxygen. Obviously not live for much longer.
- Prosthetic limbs.
- Leftover pizza.
- Road signs.
- Used tampons.
- (Probably) stolen hub caps.
- Every sort of sex toy you can imagine, and several you can’t.
Things she has seen people taking on planes, in luggage or on their bodies.
- Cock rings
- Chastity belts
- Dildoes
- All sorts of porn mags
- Cooler full of meat
Your pump shouldn’t raise an eyebrow. Call the airline and check, if it worries you.
