No need to fret. I have always had a downward curve, but hopefully in a couple of years I will have a downward curve and a huge penis. That will make me more that content. If I had a straight penis and was offered to get a crooked penis however substantially larger, I wouldn't even hesitate. So in my eyes, I really don't see why you are complaining, and curvature correcting takes LOOONG time. I have barely managed to affect mine, so I seriously doubt that you would have had more luck in a shorter period. From what I have observed it will likely take 2-3 more the amount of time to straighten a curve than reaching one's goals. Not certain though, but I will report back in what 6-10 years if you are still around and tell you how things are going.
