when i was about 5 or 6 my friend jason (who was probably about 10 or 11) i told me that condoms "stopped women having babies" when i asked him about one that was lying in the gutter.
for a good few years this explanation was interpreted by me as meaning that pregnant women used condoms to stop themselves giving birth by inserting one into their vagina and the condom somehow "catching" the baby. i thought it made sense, ie. if they were out shopping and having a baby was inconvenient, pop one in, problem solved.
