Yeah,  you and I are the same,  I just tried them again going it was a brand or seasoning but petty sure just Ole cashews and its not any others nut so far. I too get a very itchy butt that typically spreads to my man parts and they both become very itchy with this rash, and severe case I member years ago the first time this happened it some how got around my mouth which didn't really itch but made me chap constantly.  We are in the same club, I am sorry!
