As you jelq more and more and get more expierence you will find out that you can kegel just as you are ending a jelq stroke and then pump some fresh blood into the bottom of the shaft so you can maintain a more engorged dick when jelqing. Jelqing takes time to master. What I mainly try to concentrate on is as I count and do each jelq stroke with each hand I try to consitently with good timing try to get the same slow pump feeling of the blood flowing up the shaft. I also for good measure will throw in 50-100 downword and upward jelq strokes to work all parts of the shaft. One thing I’ve learned is when you jelq upward, if done right you actually build a erection up, if you jelq straight down with a overhand OK grip you tend to lose a erection unless you got the timing of the strokes down. Hope this gives you some ideas and helps some… :)
