Don't tell me you take this article for serious. Did you even check the author?I'm no expert on the subject but African tribes have been doing penis enlargement for years, it seems to work for them. It seems that they usually start very young, that might have something to do with it, again, not an expert on the subject.
Some tribes in Southern Sudan and many parts of East Africa have longer than normal penises. They achieve this fit through the usage of a herb locally known as 'Entengo' and exercising the penis.

Seriously, there literally are clinical studies out there that show that it works to an extent. Yet I have to read nonsense like that the penis is mostly made out of ligament and that this is the reason why you can't gain length. Furthermore the Koteka is no stick and it's not existing because they broke their ligaments
