I have dry skin. When the humidity drops to a certain point, the dry skin starts to itch. I know not to scratch it. When I scratch it, it only itches more. So I hold off. Until I slip. Fall off the wagon. Scratchhhhhhhh! It feels so good. Then it itches more, then I scratch more. And more and more.
I call it ITCHGASM. Sometimes, almost as good as the other gasm.
