hell, i've had people who've seen my penis up close and personal, as well as having it in their hand and mouth, guess it as closer to 10 inches. i'm not sure if those people just have no sense of distance or if they've been lied to by other guys with smaller dicks claiming to be much bigger throws their estimates off...which is to say, if a girl has been told by a guy with 4 inches that he actually has 7 inches, or even another guy with 7 inches claiming to have 10, then her sense of penis size would be skewed. lol
