Your logic is flawed as is your understanding of human male physiology. Anyone other than myself puts their fingers near my rectum, it had best be a prelude to a colo-rectal cancer screening, or I better be otherwise too enfeebled to wipe my own behind after defecating. I find anyone's digits working the wrong way up that no entrance road, I'll know what's up and they'll quickly find out how much I don't like it.
