There's been a separate thread about finding a legitimate 10 inch penis that's been running for many years now. A $10,000 reward to the owner and another $10,000 as a referral fee to someone who finds a legitimate 10 incher and brings them forward.
Years and years have gone by, with well over 1000 posts, and nothing close to a legitimate 10 inch penis has ever been shown. A few (2?) truly huge and extremely rare ~9 inch penises have been found. Funny how so many people claim to have encountered a 10 inch penis, but with $20,000 available to grab, not 1 person has been able to provide proof.
Sooo, back to your question about 9 inch penises, read posts numbers 7 and 8 above. ( inches does exist, but they are extremely, extremely rare.
