The text you're referencing is from a site selling their version of coaching. As a coach myself, I'll state the following (for free):
Almost every man has a penis. Those who do and are interested in enlargement can attempt the exercises for themselves and reap the benefits. They can educate themselves completely just from the information on this site alone- so there's no excuses!
Those who doubt it without even giving it an attempt will never know what they're missing.
Either way, any method you undertake will require education and work.
