hi i don,t have much knowledge as regards penis enlargement but i can assure you that large or small its not the size that counts its how you perform with it..
Is there a medical reason that you ask the question? or are you just self concious about your penis?

i can research if you like..as you also can on google.

Penis enlargement is possible. I don't believe that pills work, however. And I have heard mixed things about the penis pump so I don't know if it has any longterm benefits. But there is a surgery for penis enlargment. There are several names for this- penile augmentation, penile enhancement, palloplasty- that you can research online.

You can sent me a private message if you want further details.
