Do I have to try and maintain full erection, throughout the erect stretches, or is ok if I lose some erection.This is what I do.I get an almost 100 % erection, kegel the head, grab it, and pull hard outwards.Now If I try to relax my Pelvic floor, aka Reverse Kegel, I cant maintain 100 % erection, it naturally decrease by 10-20 %.Is this ok, or I should kegel for the entire one minute, in order to keep max erection the entire time?
