The jelq will never be discontinued. Jelq is a fluid displacement method for PE. What does that means? SSJ is to hold the blood in place, to be squeeze, compressed, and provide expansion. Jelq is to move the blood and plasma guild buildup in the skin to move into the lymph drainage line or out of the tissues and black into the blood vessels.
Jelqing downward from the base of the penis to your glans, you are pushing the fluid and make them collect into the lymph drainage line. You are also force the blood down to the glans by compressing the blood volume in the blood vessels to a terminal point of the penis, making the penis balloons up even more. Think of it as a directional SSJ.
By jelqing upwards from the glans to the base of your penis, you are force the blood flow out of your penis, including any build up fluid in the penis. Remember the angion methods we discussed earlier? This is practically mirror the Angion method at a low pace.
No. Normal jelqing is too low if an external pressure on the penis for the tissues to build resistance to unless you are choking the life out of it. Jelqing should be a moderate pace of lightly two to three fingers grips. If you feel like you are choking it similar to hard masturbation grips, that's not the normal jelqing. That's directional SSJ.
