New routine solves old problem

Ever since I started PE, I have mainly done Jelquing at about 75% and hardly ever at 50% for length, which I need more of than girth. This is because every time I try it at 50% I get too erect. Also my hands are too small to trap much blood at 50%. I just got a PowerJelq and I was going to do 15 min girth jelquing by hand and 15 min length jelquing with the PowerJelq. What do you vets think? Any suggestions?

Actually I find it pretty difficult to operate the PJ with only 50% erection, I do it the other way around; hand-jelq for lengh and PJ for girth @80%
