no, i'm not referring to the scanty lacey types women put on that drive men crazy.
i meant the cotton or polyester types that little boys of school-going age should wear. if they don't put one on, one day in their haste to zip or unzip their pants, a bit of the foreskin may get caught & ouch! it's not a pleasant experience for the boy, his teachers or parents.
just tonite we had such a boy - 7-years old & his "little brother" was caught as he was unzipping his pants to pee. this is worse than getting caught zipping up because he HASN'T peed yet & the pain has made him fearful of peeing. by the time he reached hospital, the discomfort of his distended bladder is causing him more distress than the pain from the zipper. poor kid!
anyway, the zipper was released under general anaethesia & a circumcision was subsequently done to reduce the risk of future "accidents." both his parents have been advised to encourage the boy to put on underwear from now on.
and as far as i know, little girls are spared this little embarrassment.
