I have the same problem, except mine bends to the left. Usually you can clearly see that one chamber is bigger than the other. In my case you can even see extra rings on the bigger chamber. I recently started jelqing to the right. I find that if you use an ok grip on the same hand which direction you are jelqing, and jelq in that direction, you get beter expansion in the undersized chamber. For example, i need to jelq right to correct my left curve so i switch from the reverse ok grip to a regular ok grip on my right hand while keeping my left hand grip the same. Then I proceed to jelq in the right (opposite my curve) direction.
I am also experimenting with gripping my cock the other way that you usually masturbate with. That is, with the thumb and index finder in the inside, and pull a bit out while squeezing in an erect state. Since you have 4 fingers squeezing the smaller size while only the thumb squeezing the bigger side you can feel greater pressure in the smaller side.
I just dont want any more curve than I already have , and if you continue with the usual routine the bigger chamber will get even greater and you will have an even bigger curve. At least it isnt peyronies or however you spell it. That usually an almost unusable curve with plaque builtup in the shrinking side.
I wish you luck with your curve correction. Hopefully you can make it straight again quickly since this is a recent occurance.
