I know I'm late to the cock comparing party, but thought this might be some useful insight. While in college I had a private meeting with a young, sexy Sex Ed. grad assistant for research on a project I was doing for another class. Our conversation turned to penis size and, according to her, research shows that the average erection is 5.25 inches. Furthermore, the BBC is a myth as on average black men's erections are just a pubic hair under 1/4" longer than white men's stiff ones. Again, according to her, if your erection is at least 6" you are in the large cock category (my words, not academic vernacular).
