Clamping with left hand jelqing with right.

When I jelq I clamp with one hand and jelq with the other. Question I have is this, the hand that I do not jelq with, the one that holds the penis, should I clamp really hard on my penis or have a relaxed hold? Also did some research on clamping isn’t it the same as just holding your penis really hard with one hand for a long period of time, lets say 10-15 minutes or so. What I do is this, when I jelq lets say I start holding my penis with my right hand and jelq with my left I do that 60 times 1 jelq = 1 second then I switch hands and so on I do this 10 times = 10 minutes, but when I hold my penis I hold it hard to the point where I’m technically”clamping it”. Thoughts anyone?

Right these are basicly clamped jelqs. Though, a clamp can be more intense IMO.

Starting out it is better to just switch the hands jelqing up without holding the base tightly.

Does it work should I keep doing what I’m doing?

It might work. this is always individual hitting that right amount to gai nand the art of PE.
If you feel good and you get temporary gains and then visible gains then keep doing it.

If you start out doing this right away I would say its too intense and normal jelqs like explained in newbie routines are much better.
You always want to use the least amount of intensity to gain as with a too high intensity the chances of just toughening up your dick are there.
