I have to chuckle at the 'dry lather' thing, everyone using straights remembers it. I don't remember that dry lather caused irritation, it became sticky and all our lives our brains have learned that if the blade doesn't move, push harder.

That works for everything but straight razors! You have to 'unlearn' the push harder instinct and fix what's causing the razor to not move.
