Dude, do the jelqing exercises, and see what happens. All of us "only" have what God gave us, but we all know that what God gave us is malleable during our time on Earth, so I say work it.

Another Site I've seen that's SUPER devoted to working with "only what God gave you" is Thunder's Place Free Penis Enlargement Forums

Best of luck to you.

EDIT: I noticed that this site automatically figures out the name of the site of the URL you posted, and links it for you. And I wanted to say that I am not affiliated with that site, and have never even posted there (though I have registered there). The super-pro auto-link-and-name-the-site logic of these forums is astounding to me. Cool feature at this board.
