when i was about 7 or 8, my friends and i would always go swimming at our health club's swimming pool. one day, we found a condom floating in the water. i picked it up, and my friend said it was probably a lotion sample from the locker room. we opened it, and we thought it was a bathing cap for your boob, (it was probably an XXL) we always thought that was incredibly funny until a few years later, after we knew what condoms were, we were looking back, and suddenly we all realised that what we were playing w/ was a condom. we were horrified and embarresed for weeks.
