Am I doing my suction angle right?

Suction hanger between 4-5 lbs. Erect length is 5.75, flaccid is 6.0 (I guess most people are shorter flaccid so idk.

I am laying down with the tension between my legs. So the angle is straight down. When I do this the skin starting from my pubes down to my base makes a triangle shape with the tip of the triangle on the base. I can’t tell if its just the skin stretching or the actual ligaments. It feels very taught though. The rest of my dick doesn’t feel a stretch at all. When I feel it at 4lbs its still very flaccid. The tension is all being held by the ligaments or skin from the top.

When I squeeze my kegels there is a pull response from 12-3 o clock and 12- 9 o clock. On thunders place it seems this is relevant to which angle you should start with. Hope it helps with the advice. I’m after length.
