first of all, are you using cablecuff?
this is my weapon of choice. Be sure your shaft is somewhat slick and not totally dry.
Click it closed somewhat and slide it down as far as you can. Next, with your hand palm down on your fat pad, place a finger on either side of your shaft and press down on the fat pad and with the other hand, push the clamp down towards your fat pad as well. If no one is around, you can begin clicking it shut. (makes noise, and i have to be careful about noise). If it starts to grab skin, then using your forefinger that you pressed your pad down with, slip it between the clamp and your skin where the teeth meet the "clicker" (to lessen the grab). Don't close the clamp all the way, unless it's loose on you. Next with your right hand, tug your shaft away from the body as the remainng hand pulls the clamp towards your fat pad. In essence you are pulling the thread thru the eye of the needle. You can jelq some at this point as your shaft "should" start to grow a bit. Be sure to keep the clamp held tight to the body as you tug. Stretching and jelqing the area "clamp to tip" is going to give you the stretching you need for length and also work on the girth. Done properly it works. I think i am a difficult grower and i am still getting results.
