Wonderboy, even compared to some of the big dudes on here, and the "photoshopped" images that people pass off as real, Tommy Lee is huge. That meaning that having a cock that is 9'ish inches long (hard) is huge. For one, this forum is a magnet for guys who are excessively huge, people who want to see cocks, and guys who want to pretend that they are huge. Don't be fooled, a 9 inch cock is rare and very large. Cocks truly over 9 inches are "white buffalos" and not that common. Reports about Tommy Lee are likely pretty accurate seeing as he is probably the only one on the list with widely available video evidence to back it up.
I found the list funny because, as stated before, it appears that everyone who plays an instrument has a huge cock... or at least the guys in need of publicity do. The list is based on submissions from people who were (allegedly) with the musicians. Put little faith in it.
