Yes, I know well what you're talking about. As a boy who didn't wear jeans, because they were cut too tight for my build, I had to wear "slacks" which wore out right below the crotch. (My mother used to have to patch them--ugh!). Later, as I slimmed down, I wore jeans and had no further problem with "crotch rot!"

Now, however, as I begin to wear kilts, I find that my thighs do indeed still rub together and it's compounded by the fact that my scrotum, which used to be kept in check by a pair of cotton briefs is now caught between them! Not that my jewels are getting crushed, but I'm wondering how this will play out come summer, when things get warmer! Is there potential for "crotch rot" in the form of a rash?

(Ah, the topics we get into on this forum!!!)
