Mouse under the rug

I can feel the “mouse” but I can’t yet trap the blood to the point where my cock is swelling like he says. I’m not giving up on this one. It feels like there is something there. Like a total cock clamp excercise ( even the hidden base would get expansion) if I can get it right.

It’s interesting to get in touch with the ‘inner cock’ … Basically I have been gripping with my 3 biggest fingers on the underside of my scrotum / through the scrotum and the thumb on the top of the penis as close to the public bone as possible. The “mouse” runs forward when I kegel. I need to be hard to feel the mouse shoot forward at all. It feels like the ejaculatory spasms.

Is it pinching or pressing? I guess for pinching you would need the thumb. Did somebody else feel good pressure when doing it? Can you explain how you did it?
