I used to believe that sex had something to do with the long chrome handles on public urinals, and that they would go into your butt, and make your butt cheeks blow up like balloons - not round balloons, but long carnival balloons. Picture people with 4 foot long buttocks sticking straight out the back of them. Don't ask me how this really related to sex, but I was sure this was it for a long time.
