What can i do to get a bigger penis without spending money?

Different parents: The only way would have been to be born to different parents w/different genetics. Be satisfied with what you have; it's much better than none at all. Remember, it's not how big but how well you use it. There is nothing you can buy, eat, or waste your money on at the store or internet that's going to make a difference in the size of your penis, just shrink your wallet.
