Why do we have so many members here that don't believe that PE is possible and that feel the need to comment that "PE doesn't work" at every available opportunity? Have these gentlemen actually taken the time to learn about PE and its related subjects? Why they would even be on a PE forum without taking the time to learn about it is confusing. Although there's plenty of evidence to the contrary, non-believers are entitled to their beliefs; but there's no need to try and discourage other men from trying to do something that makes them feel better about themselves. As long as it's done safely and you're willing to commit to it, PE exercises enlarge the penis and strengthen it as well.
