Ok, this one’s a little bizarre. In response to the comment towards the end of “Why does the penis shrink when it’s cold?” re: Singapore health scares regarding penile inversion (always wanted to write that), that’s not exactly all there is to it.
Let’s see, how to explain this. There is an extremely rare psychological disorder known as koro, which, as I understand it, has been documented in Indonesia and other regions in Southeast Asia. It is characterized by an irrational fear of the penis withdrawing entirely into the body, and is generally accompanied by the sufferer hanging on to the selected organ for dear life, sometimes for periods of days at a time. As far as I know (and hope), there is no medical basis for this fear.
I don’t have my references in front of me, sorry, but I know that I have seen write-ups on it in past issues of Fortean Times, possibly in one of the Fortean Times books (Strange Days), and in News of the Weird archives. While I realize that the Fortean Times is probably not the absolute most legitimate source for news, it seems to be fairly stable and reliable regarding this sort of phenomenon.
Further information would be absolutely NOT useful in any way, and is therefore desired.
