What would you say is the average size of flaccid penis? Of course the size is smaller if measured properly, the penis is horizontal with the floor i.e. the penis doesn't hang freely. Therefore a hanging penis looks longer than it really is. What would be the average flaccid penis based on your experience on nudist beaches, locker rooms, showers, sexual encounters? How often do you see big flaccids? Tell about your experiences. I've read that 3.5 inches would be near the average flaccid size, but of course the median size would be a bit smaller than this. What would you consider small flaccid size? What about big, huge? Is 5 inches big? Is 5.5 inches flaccid a very rare occurence? 6 inches never heard of? My flaccid size is between 5 and 5.5 inches, but I don't know how I compare. It doesn't look big to me, but the glans hangs much lower than my ballsack.
