Apart from surgical methods, there is no clinically proven method to increase penis size. The problem is that there are a lot of unscrupulous players making this claim for pills an oils that they sell. It is best to stay away from people who make such claims. Also, worries about penis size are invariably unfounded, as most men who think that they need to increase it, have a normal penis. And it does not even matter when it comes to the partner's sexual satisfaction. Anyway, you can just see how you compare, size-wise, to other men on the basis of a scientific study right here.
