i used to live on the coast... virginia beach. i noticed i hung to the left during high tide, and as the tide changed, it moved. many nights it was mighty dark out, so i could stand nekkid on the beach and as the tide moved out i could see myself gradually moving to the right. hard right, no pun intended, during low tide. hard left during high tide.
and since tides are affected by the gravitational stuff of our moon, i became a modern day pagan watching my dick move while sucking down brews on the beach, and watching the tides change. ah... what a life that was.
btw... there may have been some other chemical factors involved in my observations. but that is just heresay.
