i think it was Roccodart or Zomb131 which said to me that the penis is not a muscle, so therefore it cant be trained to get bigger like one.
and if jelquing does work, and that forces heaps of blood into the muscle to make it bigger.. well then that would be the same as taking viagra, right?
no matter how you do it, blood is still going into the cock one way or another. lol
personaly i dont beleive in jelquing. its almost the same as masturbatting exept all u do is not reach orgasm pretty much and the way u move ur hand(s) is different
also, think of all the porno's or guys you have heard or seen where the guy DOES get laid but his dingaling is like only 5-6 inches at best sometimes less than that.
and say the penis COULD be trained like a conventional muscle like a bicep or something, what would you do to make it grow?
