making lower penis shaft softer

sounds crazy? but that´s what i want!

my problem: i do powerjelqu and i realized that i can do these jelques better on the upper half of the shaft. the lower one is kind of hard, so i have no possibility to get a grip with the pj and move much blood to the head. it is like my skin (which i use to move the pj) just rushes over the shaft and can´t take too much blood with it. it is kinda difficult to describe.

my fear: that i get a basball hat penis… because the pj just works fine on top, because the tissue is softer and the pj can push more blood to the head (i have a better grip)

has anyone any solution? perhaps erect bends at the lower part?
