Question regarding the science of Jelq

Hello everyone again,

Just a quick question regarding the process of Jelq. In the manual it says “forces blood through the penis causing internal pressure. Thus, creating microtears in the structure of the penis” I just wondered if whether I am doing jelq wrong.

So, my thoughts in how I jelq is to make an “outside pressure” thus creating microtears. Meaning, I kind of disregard restricting or pushing blood flow from the bottom up and focus on my hand power, targeting the CC and CS.

I guess my question is, Should I need to visually see my penis swell from the blood rather than hit the smooth muscles with my hands? Should I have a mindset of collecting blood in my penis rather than “training the muscles”?

Thanks,
