lower your body fat... get good control of your lower abs and pc muscle..the better control you have of that region..the more cock control you have..."it's not a muscle" is what i hear all the time. Sure, but there are muscles all around ur cock.... PC and prostate muscles are key in any cock development...lots of blood flow, keep those heavy hangers healthy...every time you edge spend some time doing kegels and really letting those bones get as thick and turgid as possible...then hold..repeat..let it breathe...take it to it's limits again.. really force those veins out....flare that head past leaking. dick pinned to your abs...give a 10 count hold and relax..stay healthy
