I say get as big as you want to. The wonderful thing about Penis Enlargement is that you determine how big you want to become. AND, you can decide along the way what size suites you best. It's not like you wake up suddenly one day and all of a sudden have a much bigger penis. I have not known of anyone who has made sizeable gaines who has had issues getting erections later on. I think the few individuals mentioned above probably also have other issues going on that could cause them to have erection problems. Alcohol/drug abuse, stage fright, or stress. Who knows?
