I'm new to this forum, but not so new to the "law of attraction". In a former time in my life i was a devout christian and always meditated on a few verses from the bible that tend to back this up. such phrases as: "as a man thinketh so is he".
and there's a phrase in ecclesiastes that speaks of "casting your bread upon the water and in many days it shall return to you." There are also spiritual laws that speak to this (ie reaping and sewing).
Now I didn't post here to try to interject religion but just to say that something of this nature is possibly beyond our ability to "prove" or "fact find". It, like a lot of things in life is about "faith" which is what you believe. Not neccesarily religious belief. In fact, I think a good definition of self-confidence is a strong faith in yourself. And that's why most of us here. Not to have a dick long enough to trip over (a guy can dream can't he) but to have the confidence that said member engenders.
It seems then like a cycle: You want the confidence that a big penis provides. You have confidence your Penis Enlargement exercises will work so you stick to it, that confidence goes out (along with your hard work) into the universe and reverberates and comes back to you in gains which gives you a bigger UNIT, which gives you more confidence which encourages you to continue your Penis Enlargement etc...etc..etc...
