I'm trying to start a routine up but I've noticed something when I try to jelq. When I make the OK sign and pull up, all that really happens is my skin moves up along the shaft. If I hold the skin fairly tight with one hand and jelq with the other then I think that produces the desired effect, but just one handed nothing really gets done. I am circumcised, by the way. Am I doing something wrong? Not holding it hard enough? Should I just use the two hands? What's the deal? Thanks in advance.
