my gosh, is there even any such thing as having a 3 inch penis ???

Reply:Because, relying on self-reporting of penis size is problematic, since some patients exaggerate or are unable or unwilling to measure the penis correctly. Also men who participate in these types of surveys often do not worry about there penis size so if there is a male that is a little embarassed there tends to be more exaggeration.
