Years ago I had to go see an Ass doc about a rear end bleed ,anyway he says get up on the examination bench face away from me drop your jocks bring your knees up to your chest ,relax & wiggle your toes ? "wiggle your toes" I say what's that about ? apparently it helps the Sphincter to relax ?
news to me ? anyway I look back over my shoulder into his eyes & tongue in cheek say "you know usually you have to buy me a couple of drinks first before I let you get this far " his look was priceless

& no, I'm not Gay. Not that there's anything wrong with that....
