For the past 3 years I have been conducting an experiment on myself and some IRL friends, with the intention of growing our male members. There have been surprisingly consistent progress for all of us regarding growth. I also used to have erectile dysfunction, but this change in lifestyle and exercises that I have been doing cured it for myself and a few of my friends. If you are interested in learning more about what changes I implemented DM me, and I can go more in depth.
