Just a heads up since you’re new: alot of folks around here would probably ride you about this thread, since you could find the answer to your question from a bit of searching.
However, since I had the same dilemma and had to find my own technique to jelqing despite all the stuff I read, maybe I could help you out..
For me, it took a while to find the right level of pressure (I was too overzealous with everything, so excited to get more size). The best advice I can give to you, and this pertains to 99.9% of P.E., don’t over do it. Take it easy. So as far as your jelqing question goes, this means start out with a very light pressure. Just enough to move some blood around in there and get a light workout. Look for your P.I.’s, and very slowly and gradually increase your strength of grip/pressure and everything.
Just take it easy, start light and move from there if all goes well.
Happy gaining!
