Name For This Exercise?

I would like to know if there is a name for this maneuver and if it has any potential, good or bad, for penis shaft girth.

Basically I do a left hand Ok grip at the base and squeeze. Doing this at 50-60% erect. Then I use the other hand and squeeze below the glans with an Ok grip. The mid-shaft swells up to a big girth with veins bulging. I hold this to a 10 count and let go. I do this 5 times.

I do the Sadsak head exercise for the head and I thought this might work for the shaft.

Thanks.

Looks similar to squeezes.

Look for horse 440 with the head modification. I forgot the name. But search horse 440
