This is GREAT that you explain it so thoroughly so men don't cause more problems later down the line. I've never heard to wear it for 2 0r 3 hours at a time or to apply it in different areas each time. It's a device that improves quality of life, but it's not the end all, be all - you have to use it responsibly.
Very interesting, until recently I hadn't realized that Mario updated his favorite way to tackle ED and it's a relief! Although what he previously suggested was pretty good, it was a real pain to follow... I just go'ogled the latest in Mario Volpstein’s Thunderous Erections, it's so much easier and potent now!
