Clench my ass
I hardly do it any longer, and I'm not writing to get advice on how to "cure" it, but I wonder if anyone else does anything similar.
When traveling somewhere by automobile, I will clench my butt when I pass posts that are on either side of the road. I wonder if it's a technique I use instinctly to calm myself down while driving. I've read that the stress we have while driving is more than we realize.
Anyway, I'm not embarrassed, just curious. Do any of you "suffer" from the same "affliction"?
