How tight do you grip

Hi all, this is my first post(I’m an excellent lurker)
I just have a question concerning the jelq grip. I’ve had 3 sessions so far but even after reading and listening to everyones great advise on technique and such I’m still a bit uncertain about the feel of the grip. Should there be a feeling of real pressure or should it be more relaxed? I don’t like the idea of my knob popping off into the sink mid jelq so if anyone can soothe my fears Id much appreciate it.

One more thing, have the videos been taken offline cause I can’t seem to download any of them?
Thx B.R

Definately one of pressure. No you dick will not fly into the sink. Try this, relax your mind, take a deep breath, and perform the jelq. You should feel blood moving up the shaft but not back down. Looking at you dick everything above your grip should be expanding and most times the head will be shining brightly (in a sense).

Yeah that describes it.
