Well, the only problem with being big is that you can't do it to a chick from behind comfortably.. lol. I'm only slightly above average.. 6.5 inches to be exact ((average is 5.9 or something when measured in person. Average size gets exaggerated through online polls who's results are pretty sketchy)) Anyway, my girlfriend is pretty small, and we can't do it from behind. I poke her innards or something and it ends up hurting alot. Width is way more important anyway.
