First I want you to know that so far your manhood is able to perform it's function of urination and copulation, you don't have to worry about the size. Also, I want you know that there is practically no medically certified drug for penile enlargement. You should also note the size of your penis can also be inherited from the father and if that's the case, there is little that you can do about it.
There however some surgical procedures that can be done to enlarge it for you. They are expensive and carry their own risk.
