Yes ) My bf told me that for past few months he has seen a very big change in length of his penis. and it is just because of my sucking. I was laughing at this but he told this is right and proved in scientific theory that when we take work from any part in excess such as stretching it always help that part grow longer than rest.
Although I believe its possible (temporarily), good luck getting the people here to understand: http://www.lpsg.org/251787-its-going-to-sound-like.html Granted you didnt give any specific measurements and although I didnt have a ruler I might have exaggerated a bit, either way. Im willing to bet the majority here wont give this much weight.
Of course if that were true, with all the pulling , sucking, stretching our dicks get...we'd all have to have custom three legged pants tailor made, right?
