The Aguilar Legend started back in the early 1300s in Spain when a man named Andres Aguilar had to save his dying family from the deadly plague. One night he and his friends were drunk and they found that Andres had a large penis size. They thought that he could make money off the thing and pay a doctor to cure his family. Andres thought it was brilliant too! The Aguilar Legend is that every male decendant of the Aguilar family has a large penis.
The Aguilar Legend is known to have reached as far west as California. A great example is Enrique Aguilar from Barcelona.
