if you are sporting a kielbasa, when flaccid then you should consult an adult film producer.
if you are expecting a kielbasa, then you will be sorely disappointed throughout your life.
excessive exposure to porn , which uses as it's male performers men who are "Statistical Outlyers" (thats a nice way of saying freakishly large cocks) like Ron Jeremy, but even more frequently, individuals who had used devices to artificially enlarge their penises, such as weights, vacuum pumps, traction devices and cosmetic implants, with subsequent loss of function, sensation and potency.
these individuals are often strongly narcissistic, self absorbs and intensely shallow, who believe having an oversized flaccid impotent "Ed Begley Jr" between their knees will make them happy. it is a body dysmorphic version of the sock down the drawers.
even more insidious is the increasing use of fake dongs (they never fail and droop in the middle of a shot, and they can be whatever outlandish size the producer wishes). porn has been inflating penis expectations since the 1970's, with disastrous results.
