Well, here I am! I have several ideas for you. First, I want to ask some questions. Are you curved when flaccid? Or, is the curve only there when erect? IN order to change that curve you are going to have to stretch the underside and in so doing keep the top the same. So, you first, must never never stretch down. You are pulling the top when you do that and your stretching is going to have to be up and out but never down. Think it through.
Remember, no, never down. Start with some flaccid twists, pulling out and up. You might get erect, that is okay, just keep it up. Erect twists are good, they will stretch the underside and you will see some good progress in a couple weeks. The erect and flaccid twists are the best you can do. You will definitely see some soreness. Take it easy at first. Once you are used to this, then you can do as long and as hard as you can take. I reccomend you do a half twist, then a 3/4 and then a full. Do as much as you can. Also, you will need to be sure to get the whole schlong twisted, not just the end. If you do a twist tip to 3/4 down your shaft that is all you are going to stretch.
Next...pulling stright out, you need to do some short cranks. Hold your penis with left hand, take an inch in the right hand and crank 20 times or more. Do it both counter clock wise and clockwise. Then, move the left hand back an inch, the right hand down an inch and crank again. Keep doing this down the penis. You must do this pulling straight out or up. What you are doing with these cranks is breaking down the tissue. Keep it up..You will get some girth form this too. When you have worked clear down to the bottom, take the whole penis and crank the base. This is enough for you for now. GS
