I tended to overdo it at first, so let me explain why you shouldn’t.
To expand the penis, you need to produce forces that it isn’t normally exposed to.
The penis has many different type of tissues in it. Some will fail (read injury) before others.
Some of the weaker tissues in the penis are blood and lymphatic vessels. These need time to slowly get stronger. As they get stronger you can then start to safely produce the pressures needed to begin to expand the other tissues of the penis.
Start easy, give yourself a few weeks of conditioning. When you up the pressures used, always do it gradually and see what kind of effect it is having.
Better to take some extra time and do it safely than risk an injury that can set you back for months…or permanently!
