To give yourself an average sized penis is an easy, convenient task and one which we all recognize as the correct, appropriate thing to do. To give yourself an average size penis is objectively right. There are no situations other than kinky ass porn in which a person chooses to either have a Mandingo BBC or a micro dick. Simultaneously, it is not illegal to have a Mandingo BBC or a micro dick. Therefore the penis customization presents itself as the apex example of whether a person will do what is right without being forced to do it. No one will punish you for having a micro dick, no one will fine you or kill you for having a Mandingo BBC, you gain nothing by having an average sized dick. You must give yourself an average sized dick out of the goodness of your own heart. You must give yourself an average sized dick because it is the right thing to do. Because it is correct.

A person who is unable to do this is no better than an animal, an absolute savage who can only be made to do what is right by threatening them with a law and the force that stands behind it.

The size of your character's penis is what determines whether a person is a good or bad member of society.
